Dr. Swerdlow is a recognized cardiac electrophysiologist specializing in the care of patients with cardiac arrhythmias. His clinical interests focus in two areas: (1) catheter ablation of atrial fibrillation and other complex arrhythmias; and (2) implanted cardiac electronic devices including implantable cardioverter defibrillators (ICDs), cardiac pacemakers, cardiac resynchronization (bi-ventricular) devices, and implantable monitoring devices for heart failure.

He received his medical degree from Stanford University; Harvard-MIT Program in Health Sciences and Technology and was a resident at Los Angeles County-UCLA Harbor General Hospital. He is certified by the board in Internal Medicine, Cardiology, and Cardiac Electrophysiology. Before moving to Los Angeles, Dr. Swerdlow served as Director of the Clinical Electrophysiology Laboratory and Director of the Cardiac Arrhythmia Study Unit at Stanford University.

His previous work includes design and testing of algorithms used by ICDs to detect and differentiate arrhythmias, use of mathematical modeling to optimize electoral pulses delivered by ICDs, and development and validation of a safe and effective clinical method to determine the minimum shock strength that defibrillates the heart.

According to US News and World Report, he was voted by his peers as one of the top 4 electrophysiologists in California.

As of 2011, Dr. Swerdlow was the author of 117 peer-reviewed, original scientific papers, 140 peer-reviewed abstracts, 50 chapters and review papers, and 17 issued patents. He also serves on the editorial boards of 3 cardiac electrophysiology journals.
