Heart 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:
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.
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. To learn more about ongoing heart rhythm clinical trials at Emory, please contact:

About Dr. Hoskins
Michael Hoskins, MD, is an assistant professor of medicine and electrophysiologist who practices primarily at Emory University Hospital. Dr. Hoskins received his medical degree from the Medical College of Wisconsin in Milwaukee, after which he completed his residency in internal medicine at Emory. He was chief resident in Internal Medicine from 2005 to 2006. He then completed fellowships in cardiology and electrophysiology, also at Emory, and has been practicing here since 2010. He specializes in treating cardiac arrhythmias, focusing on ablation of arrhythmias and implantation and management of pacemakers and defibrillators.
