Cardiology (Heart) - Implantable Cardioverter Defibrillator (ICD)
An Implantable Cardioverter Defibrillator (ICD) is a device that monitors and regulates irregular heart rhythms. When it detects a dangerous rhythm, ICDs deliver an electrical shock to prompt the heart to beat at a normal rate. An ICD looks much like a pacemaker and like pacemakers, ICDs are implanted. ICDs are prescribed if you have experienced ventricular tachycardia or ventricular fibrillation, cardiac arrest, or ineffective drug therapy.
