摘要:
An implantable medical device capable of delivering high voltage therapy includes a therapy delivery module comprising a high voltage therapy delivery circuit, a high voltage short circuit protection circuit configured to terminate delivery of a high voltage pulse by the therapy delivery module in response to a short circuit condition, and a sensing module for detecting a need for a high voltage therapy. The device further includes a therapy control unit configured to control the therapy delivery module to deliver a shock pulse in response to detecting the need for the high voltage therapy. The control unit detects a termination of the high voltage pulse by the protection circuit; a truncated shock charge remaining on the high voltage therapy delivery circuit upon terminating the high voltage pulse. The control unit controls the therapy delivery module to deliver a next shock pulse at the remaining truncated shock charge.
