AICD: First of, this is a life saving device for individuals needing one! as this is inserted using surgical techniques, risks associated are bleeding, infection etc... Once implanted the device or leads can malfunction or administer an inappropriate shock etc.. Bottom line: very high benefit (stay alive), low risk.
Dr. Bennett Werner

Tiny risk: An icd is indicated for people who are judged to be at significant risk for sudden cardiac death. Not implanting an icd in this context confers a far higher risk than the procedure which, itself, is a relatively simple and low risk minor operation done with sedation and local anesthetic. There are small risks of bleeding, blood clot and infection.

Life saver: An implantable cardioverter defibrillator (icd) system has leads (wires) that are inserted through the veins under the collarbone and threaded to the heart. The leads are attached to a box that goes under the skin. The box has a computer that continuously monitors the signals from your heart for a dangerous arrhythmia. If this occurs, the icd stops the arrhythmia by delivering an internal shock.

Shock the heart: The device has the abiltiy to sense when your heart is beating in an abnormal and dangerous way which could lead to you passing out or having your heart stop. It then delivers an electric shock to the heart to convert the abnormal rhythm back to normal. The device also can function as a pacemaker if your heart beat becomes too slow.

Detection: It detects fast heart beats above a threshold set by the cardiologist and programmed into the defibrillator and delivers a shock or ATP - pacemaker override, depending on the heart rate. It will deliver subsequent shocks depending on the heart rate it detects.

Defibrillation: An automatic implantable cardioverter-defibrillator (aicd) is a lfe-saving device. The device continuely monitors the heart rhythm. When an abnormal rhythm is detected it attempts to restore a normal sinus rhythm (nsr), a cardioversion via shock or pacing alogorithms. However, when it detects a life threatening rhythm such as ventricular fibrillation it applies an immediate shock to restore nsr.
