IMPLANTABLE CARDIOVERTER DEFIBRILLATOR
What is this test?
Some heart conditions are associated with an increased risk of sudden death due to a fast and dangerous heart rhythm called ventricular fibrillation. In certain circumstances your cardiologist may recommend an Implantable Cardioverter Defibrillator (ICD. This is a device similar to a pacemaker but has the ability to detect fast, abnormal heart rhythms, and if necessary, can deliver a shock to the heart which can terminate the rhythm problem and restore normal heart electrical supply.
