Cardiac electrophysiology & Device Therapy

Cardiac electrophysiology is the science of elucidating, diagnosing, and treating the electrical activities of the heart. The term is usually used to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation (PES). These studies are performed to assess complex arrhythmias, elucidate symptoms, evaluate abnormal electrocardiograms, assess risk of developing arrhythmias in the future, and design treatment. These procedures increasingly include therapeutic methods (typically radiofrequency ablation, or cryoablation) in addition to diagnostic and prognostic procedures. Other therapeutic modalities employed in this field include antiarrhythmic drug therapy and implantation of pacemakers and automatic implantable cardioverter-defibrillators

People who have severe heart failure or serious arrhythmias (irregular heartbeats) are candidates for implantable defibrillators. These devices are surgically placed and deliver pacing, or an electric counter shock, to the heart when a life-threatening abnormal rhythm is detected. People with heart failure develop abnormal conduction of the heart’s electrical system that changes how efficiently the heart beats. Cardiac resynchronization therapy, also known as biventricular pacing, may be needed. The left ventricle is the large, muscular chamber of the heart that pumps blood out to the body. A left ventricular assist device (LVAD) is a battery-operated, mechanical pump-type device that's surgically implanted. Heart failure can develop when blockages in the coronary arteries restrict the blood supply to the heart muscle.

Removing these blockages can improve overall heart function, which may improve or resolve heart failure symptoms. PCI is one type of procedure to reopen blocked vessels. Coronary artery bypass surgery reroutes the blood supply around a blocked section of the artery. During this procedure, surgeons remove healthy blood vessels from another part of the body, such as a leg or the chest wall. They then surgically attach the vessels to the diseased artery in such a way that the blood can flow around the blocked section.
