Implantable Cardioverter Defibrillators (ICD)
Introduction
The need for treatment of Overview of Arrhythmias depends on the symptoms and the seriousness of the arrhythmia. Treatment is directed at causes. If necessary, direct antiarrhythmic therapy, including ICDs cardiovert or defibrillate the heart in response to Ventricular Tachycardia (VT) (VT) or ICDs are implanted subcutaneously or subpectorally, with electrodes inserted transvenously into the right ventricle and sometimes also the right atrium. A biventricular ICD also has a left ventricular epicardial lead placed via the coronary sinus venous system or via thoracotomy to allow Cardiac Resynchronization Therapy (CRT) pacing (CRT-D). ICD platforms also include an ICD that is completely implanted subcutaneously (S-ICD) with no intravascular components, and a wearable vest-like defibrillator for short-term use. Impulse generators for ICDs typically last about 5 to 7 years.
