A medical device includes an energy storage device, a plurality of electrodes, a memory, a switching circuit, and a processing module. The energy storage device stores electrical energy for delivery of defibrillation therapy to a heart. The memory stores N therapy configurations, each of the N therapy configurations defining which of the plurality of electrodes are used to deliver defibrillation therapy and further defining a waveform to be applied during delivery of defibrillation therapy. The switching circuit is configured to connect the plurality of electrodes to the energy storage device. The processing module is configured to control the switching circuit to deliver defibrillation therapy according to a first therapy configuration, detect a fault during delivery of the defibrillation therapy according to the first therapy configuration, and select a second therapy configuration based on when the fault was detected during delivery of the defibrillation therapy according to the first therapy configuration. |
