Overview: Millions of people have irregular heart rhythms, also called arrhythmias. Their hearts either beat too fast or too slow. These problems can be benign or they can also signal a life-threatening condition--sudden cardiac death-which is the number-one cause of death in the U.S. This program covers different kinds of heart rhythm problems and treatments. Part One: Irregular heart rhythms Causes of arrhythmias Symptoms of arrhythmia Testing for arrhythmia - ECG/EKG Sudden cardiac death Implanted defibrillators Pacemakers Part Two: Medical treatments for arrhythmias Cardiac ablation-how it works Different types of ablation PET/CT cardiac imaging Many are unaware of arrhythmias Guest: Dr. Stephen Shorofsky, a cardiologist and director of cardiac electrophysiology at the University of Maryland Medical Center. Dr. Shorofsky is also a professor of medicine at the University of Maryland School of Medicine.
