Abstract: Techniques and systems for monitoring cardiac arrhythmias and delivering electrical stimulation therapy using a subcutaneous implantable cardioverter defibrillator (SICD) and a leadless pacing device (LPD) are described. For example, the SICD may detect a tachyarrhythmia within a first electrical signal from a heart and determine, based on the tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected arrhythmia. The LPD may receive communication from the SICD requesting the LPD deliver anti-tachycardia pacing to the heart and determine, based on a second electrical signal from the heart sensed by the LPD, whether to deliver anti-tachycardia pacing (ATP) to the heart. In this manner, the SICD and LPD may communicate to coordinate ATP and/or cardioversion/defibrillation therapy. In another example, the LPD may be configured to deliver post-shock pacing after detecting delivery of anti-tachyarrhythmia shock therapy.

Abstract: An implantable medical device system detects and treats monomorphic ventricular tachycardia (VT). The system includes a sensing module for receiving a cardiac signal and a therapy delivery module including a capacitor and an output circuit. A control module is coupled to the sensing module and the therapy delivery module and is configured to detect a tachycardia from the cardiac signal and initiate charging of the capacitor in response to detecting the tachycardia. The control module performs a method for simultaneously monitoring a voltage on the capacitor and a morphology of the cardiac signal during the charging and controls the therapy delivery circuit to deliver a shock pulse at less than a programmed shock energy in response to both the voltage reaching at least a minimum voltage and the morphology being monomorphic.
