    Abstract: Implantable cardioverter device (ICD) systems capable of delivering a multi-vector defibrillation shock, and methods for use therewith, are described herein. Such an ICD system can include a defibrillation charge capacitor, a charge circuit, first, second, and third electrodes, switches, a controller, and first, second and third filters. The defibrillation charge capacitor is coupled between a first voltage rail and a second voltage rail. The first filter is coupled between the first and second electrodes, and the second filter is coupled between the second and third electrodes, so that the first and second filters can shunt EMI signals. The third filter is coupled between the first and third electrodes and configured to provide for electrical symmetry when the first, second, and third electrodes are used to deliver a multi-vector defibrillation shock. Such filters, which can be implemented using capacitors, can be used to make the ICD system MRI compatible.
