Dr. Rao Haris Naseem is a clinical cardiac electrophysiologist with over twenty years of experience in the practice of medicine.

It was early on in his career that he realized the unique possibilities that electrophysiology offered, including the opportunity to truly cure a disease—something rarely possible in heart disease. He found a passion for research in the field and has received many prestigious grants for his work. Though he relishes his role as a teacher, Dr. Naseem forever considers himself a student. His infectious enthusiasm for cardiac electrophysiology spreads quickly to patients and staff alike at North Texas Arrhythmia.
