Automatic Internal Cardioverting Defibrilator (AICD)

An AICD (Automatic Internal Cardioverting Defibrilator) is an implanted device that monitors a person's heart rhythm and can apply a large electrical shock if a life threatening arrhythmia is detected. The device is programmed to: speed up or slow down your heart and discharge an electrical shock to convert a malignant arrhythmia to a stable rhythm.


A Pacemaker is a small device implanted in the chest to help control abnormal heart rates. This device uses electrical pulses to prompt the heart to beat at a normal rate when it is too slow (bradycardia). A very slow or irregular heart rate may not be able to pump enough blood to the body and cause fatigue, shortness of breath, or even fainting. Severe brady-arrhythmias may damage vital organs and possibly cause loss of consciousness or death. A pacemaker can help a person who has abnormal heart rhythms resume a more active lifestyle.
