Emory Offers State-of-the-Art Therapies for Heart Rhythm Disorders

heart rhythm therapyHeart rhythm disorders (arrhythmias) are common medical problems that affect millions of Americans each year. Treatments for arrhythmias vary from simple medications to specialized procedures depending on the needs of a particular patient. Fortunately, due to rapidly advancing technology, available therapies are quickly changing.

As one of the premier medical research centers in the Southeast, Emory offers some of the most cutting-edge treatments available for a wide variety of heart rhythm disorders. Highlighted below are just a few of these new advances:

Wireless pacemakers

The world’s smallest pacemakers are being implanted at Emory as part of an ongoing clinical trial. The Micra leadless pacemaker is an investigational device that is about one-tenth the size of a standard pacemaker. This device is approximately the length of a paperclip and round, like a capsule. This capsule contains all of the components of the pacemaker including the battery, and eliminates the need for the wire that is part of a standard pacemaker system.

One of the key benefits of the Micra pacemaker is that fact that it is implanted using a catheter through a vein in the front of the leg. The device is inserted directly into the heart. This process is generally quicker than a standard pacemaker procedure, and avoids the need for a surgical incision. Patients who have slow heart rates with weakness, lightheadedness, or fainting may be candidates for the Micra pacemaker clinical trial. Emory is the only center in Georgia that is participating in this trial.

Subcutaneous defibrillators

Defibrillators are devices that are designed to detect and treat life-threatening heart rhythm abnormalities. They are traditionally inserted under the skin in the patient’s shoulder, with a wire (or “lead”) that travels through a vein into the heart. While these devices have proven very effective, the presence of a defibrillator lead within the bloodstream may be associated with certain long-term complications. These may include infection or scarring of the blood vessel.

The subcutaneous defibrillator is a new type of device that is placed under the skin just like a standard defibrillator. However, this new device has a lead that travels just under the skin without having to be inserted through a blood vessel. This reduces the risks associated with infection.

Cryoablation for atrial fibrillation

Atrial fibrillation is the most common heart rhythm disorder, and can be treated in a variety of ways depending on the needs of the patient. One treatment option for this arrhythmia is catheter ablation. Traditionally, ablation for atrial fibrillation involves heating, or cauterizing, certain cells involved in the generation of atrial fibrillation. One new technique that has become available in the past several years is cryoablation. This therapy involves freezing cells with a super-cooled balloon that is positioned inside the heart with the use of a catheter. Cryoablation has the potential to be quicker than standard ablation, while having similar safety and effectiveness.

Ongoing clinical trials

Emory offers several clinical trials for patients who suffer from heart rhythm disorders. These trials represent opportunities to participate in the use of cutting-edge treatments that may not be available elsewhere.

What Is Supraventricular Tachycardia (SVT) and Does It Require Treatment?

SVT heartSupraventricular tachycardia (SVT), also referred to as paroxysmal SVT or PSVT, is a type of abnormal heart rhythm (arrhythmia) in which the heart beats too fast. When the heart beats too fast, it may not function effectively, resulting in less oxygen-rich blood reaching the tissues throughout the body. SVT often starts and ends suddenly, and may not be associated with any symptoms. However, many people do experience symptoms as a result of SVT, including palpitations (rapid, noticeable heartbeats), dizziness, fainting, shortness of breath and chest pain (angina).

In most cases, SVT occurs because of a malfunction of the heart’s electrical system. The heart is made up of two upper chambers (atria) and two lower chambers (ventricles). In a normal heartbeat, an electrical impulse originates from an area in the right atrium called the sinus node. This impulse travels first to the atria, causing them to contract and pump blood into the ventricles. The electrical impulse then continues along its circuit to the atrioventricular (AV) node, where it pauses to allow the ventricles to fill with blood. Finally, the impulse reaches the ventricles, signaling them to contract and pump blood out to the lungs and the body. In SVT, the electrical malfunction occurs at some point before the electrical signal reaches the ventricles.

Common types of SVT include:

  • Atrial fibrillation (A-fib) is a type of tachycardia that occurs when multiple circuits of disorganized electrical activity in the atria replace the organized electrical activity that is normally generated by the heart. The result is fibrillation (quivering) of the atria instead of regular heartbeats.
  • Atrioventricular (AV) node re-entry tachycardia (AVNRT) is the most common form of SVT. Patients with this arrhythmia do not have structural problems with their heart, but have two pathways that can channel impulses to and from the AV node. Under certain conditions, usually following a premature beat, these pathways can form an electrical circuit, which starts a rapid heart rhythm.
  • Wolff-Parkinson-White syndrome (WPW) is an arrhythmia caused by an extra electrical pathway from the atria to the ventricles. Although some people with WPW do not have any symptoms, others experience palpitations, dizziness and angina. Rarely, WPW can be life threatening.

SVT often first occurs in children and young adults. Many controllable factors can increase the risk of SVT episodes, including stress and anxiety, certain medications, excessive alcohol or caffeine consumption, smoking and the use of illegal stimulants such as cocaine.

Otherwise healthy individuals experiencing SVT without significant symptoms may not require any treatment. However, if you have an underlying related health condition or significant symptoms, treatment may be necessary. This may take the form of medication therapy, pacemaker implantation or cardiac ablation, in which radiofrequency energy is used to destroy very tiny areas of tissue that give rise to abnormal electrical signals.

Emory’s Arrhythmia treatment program is one of the most comprehensive and innovative clinics for heart rhythm disorders in the country. In addition to offering state-of-the-art care for the full range of heart rhythm disorders, we also operate heart rhythm screening clinics at a number of locations throughout the Atlanta area.

What Is Atrial Flutter?

Atrial FlutterAtrial flutter, also called “heart flutter,” is a type of arrhythmia that occurs when the upper two chambers of the heart (the atria) contract too rapidly. The first contraction in a normal heartbeat occurs in the atria. This contraction pumps the blood into the lower chambers of the heart, called the ventricles. The second contraction occurs in the ventricles and serves to pump blood out of the heart.

In atrial flutter, the atria contract at an abnormally fast rate, but only about half of these contractions are followed by the second ventricular contraction. This causes the heart to work inefficiently and may result in poor blood supply to the body, including the brain and the heart muscle itself. If the heart and brain do not receive enough blood, organ failure can occur in the form of congestive heart disease, heart attack or stroke.

Atrial flutter can occur on its own, but often occurs in people with other conditions, including atrial fibrillation , heart failure, congenital heart defects, high blood pressure, diabetes, thyroid conditions, heart valve conditions and chronic lung disease. The risk of atrial flutter also increases following serious illness, an episode of heavy drinking, surgery or a heart attack. Symptoms may include heart palpitations (rapid, noticeable heartbeats), dizziness, shortness of breath, lightheadedness and chest pain (angina).

A simple, non-invasive test called an electrocardiogram (ECG) that measures the electrical impulses in the heart can be used to diagnose atrial flutter and other arrhythmias. Upon diagnosis, the doctor will determine the best way to control the rapid heartbeat. If there are serious symptoms, this might be accomplished with IV medications or cardioversion (electrical shock to interrupt the arrhythmia and restore a normal heartbeat). Oral medication is more common if there are not serious symptoms. Because atrial flutter can increase the risk of stroke, many people are also prescribed a blood thinner.

If you believe you are experiencing atrial flutter, it is important to seek emergency care. In addition, follow-up care with a physician that specializes in arrhythmias is also important. Emory’s arrhythmia treatment program is one of the most comprehensive and innovative clinics for heart rhythm disorders in the country. Our physicians have been pioneers in shaping treatment options for patients with arrhythmias. Our Arrhythmia Center offers screening, treatment and heart rhythm management services at locations across Atlanta .

What Is Arrhythmia?

arrhythmiaAn arrhythmia refers to an abnormal pattern or rate of the heartbeat. Arrhythmias can include heartbeats that are too fast, too slow or irregular, as is the case with atrial fibrillation , the most common arrhythmia in the United States that requires medical attention.

The normal rhythm of the heart is a tightly regulated but dynamic electrical phenomenon that changes according to the needs of the body. The heart has built-in pacemakers and “wiring” that coordinate contractions in the organ’s upper chambers (the atria) and lower chambers (the ventricles). Glitches in this complicated electrical system can cause the heart to “misfire.”

Everyone has felt their heart “skip” a beat or two or speed up in times of fear or excitement or during exercise. Too much caffeine and certain medications can also cause heart palpitations (rapid thumping in the chest) in some people. These types of arrhythmias are generally harmless.

If irregular heartbeats are frequent or chronic, they can be serious. The consequences of having an arrhythmia usually depend not only on symptoms they can cause (such as faintness), but also on the presence of heart disease or structural abnormalities. In serious cases, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart and other organs.

Common symptoms of arrhythmia include:

  • Shortness of breath
  • Chest pain
  • Palpitations
  • Feeling tired or light-headed
  • Passing out

Call your doctor if you have any of these symptoms of arrhythmia, especially if you have heart disease or have had a heart attack.

If you have experienced an irregular heartbeat, palpitations, a racing heartbeat or other heart irregularities, we recommend that you schedule an appointment with a specialty-trained Emory Healthcare Nurse Practitioner who will begin a comprehensive screening evaluation to determine whether you need follow-up care with an Emory Electrophysiologist. Call 404-778-7777 to schedule your screening appointment. You can also learn more about the Emory Arrhythmia Center online .

Emory Opens Heart Rhythm Clinics to Treat Growing Problem

arrhythmia screening centerEmory Healthcare is launching new screening centers across the Atlanta area to help diagnosis abnormal heart rhythms, or arrhythmias. An arrhythmia is a disorder of the heart that occurs when the body’s electrical impulses, which direct and regulate heartbeats, do not function properly and cause the heart to beat slowly (bradyarrhythmias), rapidly (tachyarrhythmias) or in an uncoordinated manner.

The new clinics will offer screening and, if needed, state-of-the-art care by some of the country’s leading arrhythmia experts. Clinics in Villa Rica, Conyers and Johns Creek are already operating, and a fourth location in Decatur will open later this summer.

Emory has been a pioneer in shaping arrhythmia treatment options, serving as primary and principal investigators for many national clinical trials. We rank among the world’s leaders in cardiac resynchronization therapy and have performed more cardiac ablation procedures than anyone in the Southeast.

According to the American Heart Association, atrial fibrillation (A-fib) is the most common chronic cardiac dysrhythmia and affects nearly 2.3 million people in the United States. The prevalence of arrhythmias is age-related and is expected to rise substantially as the baby boomer population continues to age.

Emory has one of the most wide-ranging and innovative treatment programs for heart rhythm disorders in the United States. Anyone who is experiencing palpitations, heart racing or other rhythm symptoms can visit one of our new screening locations to determine if their condition is serious and requires treatment by a specialist.

What Is Atrial Fibrillation (A-Fib)?

Atrial FibrillationAtrial fibrillation is the most common irregular heart rhythm in the United States. According to the American Heart Association, about two million Americans suffer from atrial fibrillation. This irregular heart rhythm occurs when multiple circuits of disorganized electrical activity in the top chambers of the heart (the atria) replace the organized electrical activity that is normally generated by the heart. The result is “quivering” (or “fibrillation”) of the atria instead of regular heartbeats.

Although not directly life threatening, atrial fibrillation often produces a fast, irregular and ineffective heart rhythm that can cause a variety of symptoms, including chest pain, decreased blood pressure, weakness, lightheadedness and shortness of breath.

There are many conditions that can cause atrial fibrillation. The most common include:

  • Hypertension (high blood pressure)
  • Coronary artery disease (CAD)
  • Heart valve disease
  • Heart surgery
  • Chronic lung disease
  • Heart failure
  • Cardiomyopathy
  • Congenital heart disease
  • Pulmonary embolism
  • Alcohol use

Recently, it has been discovered that high-level athletes competing in endurance sports are at higher risk of developing this condition. Of note, the risk of atrial fibrillation increases with age, particularly after age 60. However, in at least 10% of cases, atrial fibrillation occurs without any identifiable cause or risk factor. This is called “lone atrial fibrillation” and can be successfully treated in many cases.

Atrial fibrillation was once thought to be a harmless condition, but we now know that it can contribute to additional heart problems over time, including stroke and heart failure. Only a few years ago, people suffering from this common heart arrhythmia were told they would probably have to live with the problem. Today, however, an increasing number of people with atrial fibrillation can be treated and cured, thanks to innovative therapies and procedures such as cardiac ablation, available through the Emory Heart & Vascular Center’s Atrial Fibrillation Program.

With sites at Emory University Hospital, Emory University Hospital Midtown and Emory Saint Joseph’s Hospital, Emory’s Heart & Vascular Center has one of the few truly comprehensive atrial fibrillation treatment programs of its kind in the Southeast.

Is Too Much Coffee (Caffeine) Bad for the Heart?

For those of us who frequent the local coffee shop for our morning pick-me-up, the answer to the question, “Too much coffee?” is always a resounding “Never!” But the lasting, jittery feeling really should make you wonder.

While caffeine energizes and rejuvenates, too much of anything is usually not healthy. Each day, about 90 percent of Americans consume caffeine in one form or another. Chances are, if a person consumes more then 400 mg of caffeine per day, they’re likely missing out on other more nutritional beverages and/or skipping meals.

The American Heart Association states that “Many studies have been done to see if there’s a direct link between caffeine, coffee drinking and coronary heart disease. The results are conflicting. This may be due to the way the studies were done and confounding dietary factors. However, moderate coffee drinking (1–2 cups per day) doesn’t seem to be harmful.”
While the caffeine content of coffee is not in and of itself harmful to a person, additives such as the cream, sugar and artificial sweeteners definitely have an impact on the body, especially the heart.  Caffeine stimulates the nervous system, which also speeds up the heart rate. Heavy caffeine consumption has been linked to certain heart problems such as, mild arrhythmia, which is an irregular heartbeat.

“Abnormal heart rhythms, such as Lone Atrial Fibrillation (A-Fib), considered to be the most common, can be trigged by caffeine”, says Dr. Mikhale El-Chami, Cardiologist at Emory University Hospital.

The consumption of caffeine has also been reported to increase the release of fatty acids, decrease sensitivity to insulin, and transiently increase blood pressure. These effects are unfriendly to cardiac health.

If you’re a patient with a heart condition, or if you’re at risk for heart disease, your doctor can help you decide whether or not limiting your caffeine consumption is advisable.

Lone Atrial Fibrillation (A-Fib) – Takeaways from our Heart to Heart

Lone Atrial FibrillationThank you for those who were able to participate in the Emory Heart & Vascular Center Live Chat on Arrhythmias last week! You all had great questions and highly engaged. If you could not join me, you can view the Arrhythmia chat transcript here. We covered a lot of different topics. Please feel free to use the comments below to let us know if you have other heart and vascular topics you would like to cover in future live chats, and we will see if we can organize!

During the chat, there were questions I did not have time to answer. Specifically, I told attendees that I’d be posting a follow up blog on Lone Atrial Fibrillation, a less discussed type of arrhythmia that I got some good questions around.

What is Lone Atrial Fibrillation (A-Fib)?

Lone Atrial Fibrillation (A-Fib) is atrial fibrillation seen in patients younger than 60 years with no underlying structural heart disease.  It may be caused by a specific trigger or could occur without any trigger.

What are the possible triggers for Lone Atrial Fibrillation?

Lone A-Fib can be triggered by:

  • Emotional or work related stress
  • Physical Overexertion
  • Alcohol use or overuse
  • Caffeine consumption
  • Infection
  • Dehydration
  • Electrolyte imbalances
  • Drugs (cocaine, amphetamines, etc)
  • Hypoglycemia

Unfortunately, in the majority of cases of Lone Atrial Fibrillation occur without any triggers. It is probably difficult to avoid all the potential triggers for Lone A-Fib.  But when a trigger exists, it is  typically specific to each individual.  There is no consistent way to safely and effectively manage Lone A-Fib episodes, so I recommend you consult your cardiologist to ensure you are taking the most appropriate steps for your particular case.

Has Your Heart Ever Skipped a Beat?

Arrhythmia Web Chat with Dr. El-ChamiHave you ever experienced a skipped heart beat or a change in the regular beat of your heart? If so, you may have a rhythm disorder called an Arrhythmia. Arrhythmias are common in middle-aged adults. Some arrhythmias are relatively harmless, but others can be fatal if not treated. Nearly 1,000,000 people are hospitalized for an arrhythmia each year, and some arrhythmias, such as Atrial Fibrillation, are extremely common and affect over 2,500,000 million Americans.

Join me on Wednesday, August 24, at 12:30 p.m. for an interactive web chat on the topic of Diagnosing, Managing and Living with Arrhythmias. I will be available to answer questions and discuss various topics about arrhythmias, including symptoms, diagnosis, prevention and treatment, as well as innovative new cardiovascular research on the horizon.
