Personal Statement

As a cardiologist who specializes in heart rhythm abnormalities, I have witnessed dramatic changes in our understanding of arrhythmias and in treatment possibilities to improve health and longevity of our patients. Treatments that are now considered routine were unimaginable when I started my medical career. I am fortunate to have access to the latest advances in technology and a highly trained, professional team that shares a common goal of achieving optimal outcomes in patient care. But more importantly, my colleagues and I recognize that treating a patient with heart rhythm ailments requires attention not only to technical considerations but also to coping with the impact of arrhythmias on lifestyle and overall wellbeing. In this specialty, we have the ability to provide therapies that not only prolong life but also improve its quality.

My practice is devoted to treatment of patients with arrhythmias, including rapid heart rhythms such as atrial fibrillation and flutter, supraventricular tachycardia, and ventricular tachycardia. I also treat patients with abnormally slow heart rhythms (known as bradycardia). I perform interventional procedures aimed at alleviating these conditions, specifically catheter ablation, pacemaker implantation, defibrillator implantation, and cardiac resynchronization therapy.

Dr. Markowitz is a Professor of Medicine and Associate Director of Cardiac Electrophysiology Laboratories. He specializes in treating patients with arrhythmias (abnormal heart rhythms) and provides care in all aspects clinical electrophysiology. This includes the evaluation of patients with the following conditions:

-Supraventricular arrhythmias such as atrial fibrillation, atrial flutter, atrial tachycardia, supraventricular tachycardia, and Wolff Parkinson White syndrome

-Ventricular arrhythmias such as ventricular ectopy (PVCs), ventricular tachycardia, and ventricular fibrillation

-Syncope (fainting)


-Patients at high risk for sudden cardiac death, such as those with structural heart disease and those with a high-risk congenital condition (e.g., long QT syndrome, hypertrophic cardiomyopathy, Brugada syndrome, etc.)

-Patients with structural heart disease and refractory congestive heart failure


Dr. Markowitz performs the following procedures for management of patients suffering from any of the above conditions:

-Diagnostic electrophysiologic testing

-Radiofrequency and cryoablation ablation for all types of supraventricular and ventricular arrhythmias
