Electrical or rhythm disorders of the heart can range from the annoying but benign to the life-threatening, and over the last ten to fifteen years, exciting advances have been made in the medical and interventional treatment of these arrhythmias. Small catheters can be placed inside the heart via sheaths in the groin, and the abnormal circuits that cause the arrhythmia mapped out prior to delivering either heat energy (radiofrequency) or freezing energy (cryoablation) to create small scars that break the abnormal circuits. Our physicians have been in the forefront of research and development of these procedures, and we routinely treat all of the arrhythmias that can be ablated, including supraventricular tachcyardias (SVT), ventricular tachycardia (VT), and atrial fibrillation.
