About Thomas Konecny

My name is Dr. Thomas Konecny, and I am an associate professor of clinical medicine and an attending cardiac electrophysiology physician in the University of Florida Division of Cardiovascular Medicine. I am board certified in internal medicine, cardiovascular diseases and cardiac electrophysiology and practice at both UF Health Shands Hospital and the Malcom Randall VA Medical Center.

I received my bachelor’s degree in cellular and molecular biology at Westmont College in Santa Barbara, California, and my medical degree from Columbia University in New York. I was drawn towards my specialty from an elective class I took while at Columbia. I completed a residency in internal medicine followed by consecutive fellowships in cardiovascular diseases and cardiac electrophysiology at The Mayo Clinic in Rochester, Minnesota.

I am currently working on research in interactions of arrhythmias and breathing disorders (sleep apnea, chronic obstructive pulmonary disease). For our expertise in this field, I have received awards from the American Heart Association, American College of Cardiology and American College of Chest Physicians. I am the first author of the chapter on arrhythmia-sleep apnea interactions in one of the main textbooks of cardiac electrophysiology currently in use.

I am proficient in procedural ablations, including atrial fibrillation, atrial flutter, supraventricular tachycardias and ventricular tachycardia, as well as devices, including cardiac resynchronization, subcutaneous and intravenous defibrillators, laser-assisted lead extractions, diaphragmatic pacing for the treatment of central sleep apnea, leadless pacemakers and implantable devices for arrhythmia monitoring.

One thing I’d like my patients to know about me is that I have a pre-eminent dedication to their safety. When I’m not working, I enjoy Florida outdoor activities.
