Zaid Aziz, MD

Assistant Professor of Medicine

Zaid Aziz, MD, is a cardiologist specializing in cardiac electrophysiology (EP) and provides care for patients with cardiac conditions such as heart failure and cardiac rhythm abnormalities (arrhythmias). Dr. Aziz treats a wide range of arrhythmia-related disorders and performs catheter ablation for supraventricular tachycardia, atrial fibrillation, atrial flutter, ventricular tachycardia and more. He also has expertise in cardiac device management for patients with pacemakers, defibrillators, cardiac resynchronization therapies and left atrial appendage closure devices.

Along with his electrophysiology practice, Dr. Aziz is interested in investigating new therapies for patients with heart rhythm disorders. His research focuses on innovating complex arrhythmia treatments, including developing novel approaches to atrial fibrillation and ventricular tachycardia ablations. Dr. Aziz is currently investigating the use of high-density, 3D anatomical mapping techniques to improve ablation outcomes. His work has been published in journals such as Circulation, Heart Rhythm, Journal of Cardiovascular Electrophysiology, American Journal of Cardiology, Circulation: Arrhythmia and Electrophysiology and JACC Clinical Electrophysiology. He was recently appointed to the editorial board for the Journal of Interventional Cardiac Electrophysiology.

In addition to being committed to delivering high quality care to his patients, Dr. Aziz is passionate about educating cardiac fellows. As the director of UChicago Medicine’s clinical cardiac electrophysiology fellowship program, he mentors advanced EP fellows as they learn procedural skills, arrhythmia management, risk assessment and sudden cardiac death prevention. He also serves on national EP fellowship educational advisory committees to improve training for fellows. His dedication to advancing EP education is one of the many reasons Dr. Aziz received the Rory R. Childers Cardiology Teaching Award, the cardiology section's fellow's teaching honor.

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
