A cardiac electrophysiologist is a cardiologist that focuses on diagnosing and treating disorders of the electrical system of the heart. They treat abnormal heart rhythms (arrhythmias) such as atrial fibrillation, supraventricular tachycardia (SVT), Wolff-Parkinson-White syndrome, Long QT syndrome, Brugada syndrome, ventricular tachycardia. The prescribe medications and perform procedures for treatment such as cardiac ablations, pacemaker implantation and defibrillator (ICD) implantation.

Evaluation by a cardiac electrophysiologist may be indicated if you have symptoms suggestive of heart disease or irregular heart rhythms such as heart racing (palpitations), lightheadedness, blacking out or passing out, shortness of breath, fatigue or chest pain.

Cardiac electrophysiologists generally treat patients with abnormal heart rhythms such as atrial fibrillation, atrial flutter, supraventricular tachycardia (SVT), Wolff-Parkinson-White syndrome (WPW), ventricular tachycardia, Long QT syndrome, Brugada syndrome in addition to a number of other heart electrical abnormalities. They also treat patients for general cardiology conditions as a number of those diseases, including hypertension, obesity, coronary artery disease (CAD), congestive heart failure (CHF), can predispose individuals to electrical issues.
