Cardiac Ablation

Make Appointments & Get Care

What is Cardiac Ablation?

Every beat of your heart is triggered by an electrical impulse. But sometimes, the impulse travels the wrong way, which can cause heart rhythm problems like palpitations, an irregular heartbeat, or sustained rapid heart rates—also known as arrhythmias.

Sometimes, an arrhythmia can be treated with medication. Other times it’s treated with catheter ablation, which uses a tiny tube to stop the electrical signals from traveling the wrong way.

Catheter ablation can often cure an arrhythmia completely, so patients no longer have any symptoms or need medications.

UR Medicine's Approach

At UR Medicine, catheter ablation is used to treat many rhythm problems, including supraventricular tachycardia (SVT—which results in a sustained rapid regular heart beat originating in the upper chamber of the heart), atrial fibrillation (which causes a fluttering sensation in the heart’s upper chambers) and ventricular tachycardia (a rapid heartbeat in the lower chambers of the heart that can be life threatening).

Catheter ablation is performed in the Electrophysiology Lab at UR Medicine. UR Medicine Cardiac Care has three fully equipped labs for ablation and device implants, staffed by nurses and technicians who work exclusively on heart rhythm disorders. Our newest lab features robot-aided navigation, which offers even greater precision, safety, and versatility.

Catheters (very thin tubes) are threaded through a small incision in the leg up to your heart. Your electrophysiologist uses electrodes on the end of each catheter to create tiny scars on the wall of your heart to keep its electrical impulses traveling in the right direction.

The procedure typically takes three to six hours. Most patients go home the same day, but some may need to stay overnight in the hospital.
