Abstract: A medical device comprises a sensing circuit configured to sense at least one cardiac electrical signal, sense first ventricular event signals from the at least one cardiac electrical signal according to a sensitivity setting set to a first amplitude; and a control circuit in communication with the sensing circuit, the control circuit configured to determine that the at least one cardiac electrical signal meets suspected undersensing criteria, in response to determining that the suspected undersensing criteria are met, perform a morphology analysis of a first cardiac signal segment acquired from a first cardiac electrical signal of the at least one cardiac electrical signal sensed by the sensing circuit over a first predetermined time interval, determine that the first cardiac signal segment is a first tachyarrhythmia segment based on the morphology analysis, and adjust the sensitivity setting from the first amplitude to a second amplitude less than the first amplitude in response to determining that the first cardiac signal segment is a first tachyarrhythmia segment.

Abstract: An extra-cardiovascular implantable cardioverter defibrillator (ICD) having a high voltage therapy module is configured to control a high voltage charging circuit to charge a capacitor to a pacing voltage amplitude to deliver charge balanced pacing pulses. The capacitor is chargeable to a shock voltage amplitude that is greater than the pacing voltage amplitude. The ICD is configured to enable switching circuitry of the high voltage therapy module to discharge the capacitor to deliver a first pulse having a first polarity and a leading voltage amplitude corresponding to the pacing voltage amplitude for pacing the patient's heart via a pacing electrode vector selected from extra-cardiovascular electrodes. The high voltage therapy module delivers a second pulse after the first pulse. The second pulse has a second polarity opposite the first polarity and balances the electrical charge delivered during the first pulse.

Abstract: A medical device is configured to determine tachyarrhythmia evidence in a cardiac signal segment received from a cardiac electrical signal sensed during a pacing escape interval started to schedule a pending cardiac pacing pulse. The medical device may delay the pending cardiac pacing pulse in response to determining the tachyarrhythmia evidence during the pacing escape interval.
