Video Profile

Director, Electrophysiology

Dr. Kanter joins The Heart Institute at Nicklaus Children’s Hospital as the director of electrophysiology. Prior to joining Nicklaus Children’s, Dr. Kanter served as a clinical professor of pediatrics at Duke University School of Medicine in Durham, North Carolina, where he was director of pediatric electrophysiology. Dr. Kanter received his medical degree from the Vanderbilt University School of Medicine in Tennessee and completed his fellowship in cardiology at Boston Children’s Hospital and the University of Florida.

Dr. Kanter’s clinical interests include: infants, children, teenagers, and young adults with known or possible cardiac channelopathies, syncope, cardiac arrhythmias, resuscitated sudden death, or congenital heart disease; a family history of sudden cardiac death; adults with congenital heart disease and arrhythmias; placement of cardiac pacemakers and implantable defibrillators; diagnostic esophageal and intravascular electrophysiologic studies; and catheter ablation of tachycardia substrates.

Dr. Kanter is board-certified by the American Board of Pediatrics in pediatrics.

The Heart Institute LogoThe Heart Institute at Nicklaus Children’s, a world leader in pediatric cardiology and cardiovascular surgery for the care of children with congenital heart disease, serves as a beacon to families confronting the reality of a child or newborn with a heart defect. The Heart Institute offers the most innovative and least invasive approaches to  the treatment of congenital heart disease, including many first-in-the-world procedures that were pioneered right here by The Heart Institute’s own internationally renowned cardiologists and cardiovascular surgeons.
