Dr. Zadeh joined Keck USC as a member of our clinical faculty in the department of Cardiac Electrophysiology in April 2019. He is board certified in Cardiovascular Disease, Clinical Cardiac Electrophysiology, and Cardiovascular Computed Tomography (CT). He studied at the University of Louisville on full academic scholarship and graduated Magna Cum Laude. He received an academic scholarship to continue his studies at the University of Louisville School of Medicine, graduating among the top of his class and earning Alpha Omega Alpha (AOA) honors. He then relocated to Los Angeles for Internal Medicine Residency at Cedars-Sinai Medical Center, subspecialty fellowship training in General Cardiology at Harbor-UCLA Medical Center, and in Clinical Cardiac Electrophysiology at the Harbor-UCLA/Good Samaritan Hospital Program.

His clinical practice encompasses over 10 years in the greater Los Angeles area. He performs diagnostic electrophysiology studies to evaluate patients with arrhythmias, as well as curatively treats patients using catheter ablation. This includes patients with ventricular arrhythmias and supraventricular arrhythmias, such as AVNRT, AVRT, atrial tachycardia, atrial flutter and atrial fibrillation. He has gained valuable experience in the treatment of atrial fibrillation using both radiofrequency and cryoballoon technologies, though he has focused his practice primarily on using radiofrequency. Dr. Zadeh also specializes in the implantation of cardiac devices, including pacemakers, implantable cardioverter-defibrillators (ICDs), and biventricular pacemaker/defibrillators. He implants transvenous as well as subcutaneous ICDs, in addition to leadless pacemaker systems contained entirely within the heart.

His expertise has led to implantation of other transvenous devices such as the Cardiac Contractility Modulation (CCM) device (aka Cardiac Optimizer) and a central sleep apnea stimulator implant (Remede device). Dr. Zadeh leads our lead extraction program at USC, capable of removing old pacemaker wires that are malfunctioning or infected. He is the primary investigator on multiple clinical trials at Keck USC, including emerging technologies, such as dual chamber leadless pacemakers and a percutaneous technique to implant the BaroStim modulation device in the treatment of congestive heart failure. He also is a member of our clinical faculty to educate and train both general cardiology and cardiac electrophysiology fellows.

Dr. Zadeh is fluent in Persian (Farsi) and can communicate effectively in Spanish. He enjoys traveling abroad, hiking, and spending his free time with his family. As a proud alumnus, he is a passionate University of Louisville basketball and football fan (Go Cardinals!).
