Defibrillator Implantation

General Information

Under certain circumstances the beat of the heart can become abnormally fast in a very dangerous way. This usually occurs in people who already have major abnormalities of the electrical system of the heart or of the heart muscle. An Implantable Cardioverter Defibrillator (ICD) can detect such fast heartbeats and correct them by applying a series of electrical impulses to the heart or by delivering a shock to the heart.

An ICD is made up of a pulse generator, which lies under the skin just below the collarbone (usually), and 1 to 3 leads that arise from the pulse generator and go into the heart. The leads transmit the electrical impulses or shock from the pulse generator to the heart muscle.

    Atrial fibrillation is a consequence of several reversible risk factors - high blood pressure, diabetes, obesity, sleep apnoea, and excessive alcohol. Your management of atrial fibrillation must include strict control of these risk factors.
