The heart is a beautifully designed pump that relies on its own electrical system to beat and circulate blood throughout the body. Sometimes there is a problem with the heart’s electrical system – or electrophysiology – resulting in a heart rhythm disorder whereby the heart beats too fast, too slow or irregularly, which can lead to a number of complications, including stroke and even sudden death. Harvey R. Chen, M.D. and Timothy N. Ball, M.D. are clinical cardiac electrophysiologists who are specializing in diagnosing and treating heart rhythm disorders and irregular heartbeats (arrhythmias). They use a number of advanced technologies and techniques for diagnosis and management. Dr. Chen and Dr. Ball are board certified by the American Board of Internal Medicine in Clinical Cardiac Electrophysiology. There are a number of advanced technologies and techniques for diagnosis and management: Evaluation and treatment of atrial fibrillation, ventricular tachycardia and other arrhythmias Evaluation and treatment of syncope Management of antiarrhythmic medications Electrophysiology studies Ablations Holter monitors, event monitors, and implantable loop recorders Implantation and management of pacemakers Implantation and management of implanted cardioverter defibrillators (ICDs) Cardiac re-synchronization therapy and biventricular devices Intracardiac echocardiograms.
