Biography
Fergie J. Losiniecki, MD, FACC, FHRS, a board-certified cardiac electrophysiologist specializing in the diagnosis and treatment of complex heart rhythm disorders.
Dr. Losiniecki cares for patients with a wide range of cardiac arrhythmias, offering advanced therapies to restore normal heart rhythm and improve heart function. Her clinical expertise includes complex ventricular arrhythmia ablation, cardiac lead management and extraction, leadless pacing technologies and extravascular defibrillation therapy. She also specializes in physiologic pacing and conduction system pacing, innovative approaches designed to support more natural heart function.
In addition, Dr. Losiniecki has a special interest in electrophysiology care for structural heart patients, including those undergoing transcatheter aortic valve replacement (TAVR) and transcatheter tricuspid valve replacement (TTVR). She is also experienced in pulsed field ablation, an emerging technology for the treatment of atrial fibrillation and ventricular arrhythmias.
Dr. Losiniecki completed her fellowship in cardiac electrophysiology at the Medical University of South Carolina and her fellowship in cardiovascular medicine, as well as her residency in internal medicine, at the University of Miami Miller School of Medicine / JFK Medical Center GME Consortium. She earned her medical degree from Ross University School of Medicine.
