Heart Rhythm Disturbances

ARMC electrophysiologists – Cardiologists who specialize in heart rhythm disturbances, or arrhythmias, such as atrial fibrillation (a-fib) — perform a range of procedures in the electrophysiology (EP) lab to get heart rhythm back in sync. These include:

Permanent and biventricular pacemaker implantation

– Pacemakers are implanted in the upper chest to monitor heart rhythm and send out electrical signals to make the heart beat when needed. Different types of pacemakers are used for different conditions. ARMC specialists have implanted thousands of pacemakers with excellent outcomes, and we provide comprehensive pacemaker follow-up services.

Automated implantable cardioverter defibrillator (AICD) implantation

– AICDs are extremely sophisticated devices that function as a pacemaker for heart rates that are too slow and deliver life-saving shocks if the heart rhythm becomes dangerously fast. They are very successful in treating tachycardia and ventricular fibrillation, the main causes of sudden cardiac arrest.


– ARMC electrophysiologists use this minimally invasive procedure to treat persistent heart rhythm disturbances, such as atrial fibrillation, that don’t respond to traditional medical treatments. Ablation involves the use of radio frequency waves to eliminate the small area of the heart’s electrical tissue causing the rhythm disturbance, thus restoring normal electrical traffic. “Complex” ablation procedures that make use of sophisticated computer-mapping systems to locate and eliminate the source of the abnormal rhythm also are performed with great success at ARMC.
