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 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: A medical device is configured to sense first ventricular event signals from a first cardiac electrical signal and sense second ventricular event signals from a second cardiac electrical signal. The medical device is configured to determine sensed event data in response to the first ventricular event signals and the second ventricular event signals. The medical device may select one of the first cardiac electrical signal or the second cardiac electrical signal for providing input for tachyarrhythmia detection based on the sensed event data.

Abstract: An implantable medical device system is configured to detect a tachyarrhythmia from a cardiac electrical signal and start an ATP therapy delay period. The implantable medical device determines whether the cardiac electrical signal received during the ATP therapy delay period satisfies ATP delivery criteria. A therapy delivery module is controlled to cancel the delayed ATP therapy if the ATP delivery criteria are not met and deliver the delayed ATP therapy if the ATP delivery criteria are met.

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.

Abstract: A medical device is configured to determine an amplitude metric from a cardiac signal segment sensed over a predetermined time interval and determine if the amplitude metric meets an amplitude threshold. The medical device is configured to perform a first analysis of the cardiac electrical signal segment for detecting a first arrhythmia when the amplitude metric does not meet the amplitude threshold and perform a second analysis of the cardiac electrical signal segment for detecting a second arrhythmia different than the first arrhythmia in response to the amplitude metric meeting the amplitude threshold.

The therapy delivery circuit is configured to deliver an electrical stimulation therapy to a patient's heart via the electrodes coupled to the implantable medical device. The control circuit is configured to control the sensing circuit to set a starting value of the cardiac event sensing threshold and hold the starting value constant for a sense delay interval. The control circuit is further configured to detect an arrhythmia based on cardiac events sensed by the sensing circuit and control the therapy delivery circuit to deliver the electrical stimulation therapy in response to detecting the arrhythmia.
