Cardiac Electrophysiology at CVPH

Cardiac electrophysiology is a subspecialty of cardiology that deals with abnormalities of the electrical system of the heart, also known as arrhythmias.

The cardiac electrophysiology program at CVPH encompasses all treatment modalities for cardiac arrhythmias including drug therapy, implantable cardiac devices ( including pacemakers, defibrillators and cardiac resynchronization or biventricular devices), electrical cardioversion, tilt testing and catheter ablation. Some of the procedures performed at CVPH, such as complex ablations including atrial fibrillation ablation, are rarely performed in rural hospitals. All defibrillator implants, biventricular device implants and ablation procedures are performed by Dr Siouffi and Dr Loka, both Dartmouth trained cardiac electrophysiologists. These procedures are performed in a dedicated electrophysiology lab, with a dedicated electrophysiology staff. Since its inception in 2006, the cardiac electrophysiology program at CVPH has offered the residents of the North Country the same level of care found in large urban centers, but with the added convenience of proximity.

Samer Y Siouffi, MD, FACC

Dr Siouffi is  board certified in cardiology and cardiac electrophysiology, and the director of cardiac electrophysiology at CVPH. Dr Siouffi received his medical degree from the American University of Beirut in Beirut, Lebanon in 1985. He completed his training in internal medicine and cardiovascular diseases at the University of Mississippi Medical Center in Jackson MS. He then pursued a fellowship in cardiac electrophysiology at Dartmouth Hitchcock Medical Center in Lebanon NH, which he completed in 1996. He moved to Plattsburgh from Pittsburgh PA in 2006 and started the electrophysiology program. His practice is limited to cardiac electrophysiology with an emphasis on radiofrequency ablation. Dr Siouffi lives in Plattsburgh with his family and enjoys skiing and hiking the Adirondack mountains.

Alfred Loka, MD

Dr Loka received his medical degree from the Democratic Republic of Congo in 1996. He completed his training in internal medicine and cardiovascular diseases at the State University of New York Downstate in Brooklyn, NY in 2010. He then pursued a fellowship in cardiac electrophysiology at Dartmouth Hitchcock Medical Center in Lebanon NH, which he completed in June 2012. He joined CVPH in August 2012 and practices general cardiology and cardiac electrophysiology. He is involved in our outreach clinic in Massena where he provides consultative services to the residents of that area. Dr Loka lives in Plattsburgh and is excited to be part of a team that provides tertiary level cardiac care in a rural area. Dr Loka thoroughly enjoys the outdoors and hiking the Adirondacks. 

Victoria (Tori) Dow RPA-C

Victoria is a native of this area, having grown up in Plattsburgh. She moved after high school to complete her nursing degree at Albany Medical Center in Albany NY, which she completed in 1982. She practiced nursing in the Albany area for 10 years before going back to school to complete her Physician Assistant (PA) training through the Albany Medical Center- Hudson Valley PA program in 1993. She worked for a year in the electrophysiology division at the Albany Medical Center before joining Capital Cardiology Associates of Albany, where she participated in establishing the electrophysiology practice. After 16 years, she returned home to Plattsburgh and joined Dr Siouffi in 2010 and has been a tremendous asset to the electrophysiology program and to CVPH. She is a gifted communicator and greatly enjoys the patient education aspect of her position. She also has a particular interest in heart failure and is an active member of the Heart Failure Committee, which is trying to improve the care of heart failure patients in the North Country through education with a multidisciplinary approach to patient care. When not at work, Tori enjoys walking her 2 dogs (98 lb Golden Retriever and 12 lb Chihuahua) in the great North Country outdoors, as well as kayaking, biking and swimming. Tori is grateful to be back among family, enjoying the rich, beautiful, and diverse outdoor opportunities of home.
