Implantable Cardioverter Defibrillator (ICD) remains the cornerstone therapy in the management of malignant ventricular arrythmia’s for patients with high risk cardiac conditions. An ICD system contains a battery, capacitors, sensing/ pacing circuit together with an intra-or extra-cardiac lead. All ICD’s have an in-built switch (Reed switch, Hall-effect sensors, Giant magneto sensitive resistors or coils) which...
