 | | The implantable cardioverter defibrillator (ICD) is a device used to treat dangerously fast heart rates that occur in the lower chambers of the heart (the main pumping chambers). |
 | | The ICD detects both bradyarrhythmia (slow heart rates) and tachyarrhythmia (fast heart rates) and delivers electrical therapy to treat these rhythm disorders and restore normal rate and rhythm to the heart. |
 | | ICD therapy is often prescribed for patients who have experienced at least one episode of ventricular tachycardia or ventricular fibrillation, previous cardiac arrest, or drug therapy that was ineffective in controlling the tachyarrhythmia or that caused severe side effects. |
