Cardiologist (Heart Specialist)
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 abnormalitites of the electrical system of the heart. An ICD is an electrical device that can detect and treat abnormally fast heartbeats by delivering a shock to the heart. An ICD is made up of a pulse generator and 1-3 leads that arise from the generator and go into the heart. The leads transmit the electrical inpulses or shock from the pulse generator to the heart muscle.
