Implantable Cardioverter Defibrillators Manufacturers

An implantable cardioverter defibrillator is a device like pacemaker. It is placed under the skin just below the collarbone. The device uses leads to monitor every single heartbeat. If a lethal rhythm appears, the defibrillator shocks the heart back to a normal rhythm. It monitors the patient's heart rhythm, and automatically administers shocks for various life threatening arrhythmias, according to the device's programming. It is used in patients at risk for recurrent, sustained ventricular tachycardia or fibrillation. The device is connected to leads positioned inside the heart or on its surface. These leads are used to deliver electrical shocks, sense the cardiac rhythm and sometimes pace the heart, as needed. The various leads are tunneled to a pulse generator, which is implanted in a pouch beneath the skin of the chest or abdomen. These generators are typically a little larger than a wallet and have electronics that automatically monitor and treat heart rhythms recognized as abnormal.
