Abstract:
1. A method comprising: sensing a first electrical signal from a heart of a patient; detecting a tachyarrhythmia within the sensed first electrical signal; determining, by a subcutaneous implantable cardioverter defibrillator (SICD) and based on the detected tachyarrhythmia, to deliver anti-tachyarrhythmia shock therapy to the patient to treat the detected arrhythmia; receiving, by a leadless pacing device (LPD) implanted within the heart of the patient, communication from the SICD requesting the LPD deliver anti-tachycardia pacing to the heart; sensing, by the LPD, a second electrical signal from the heart of the patient; and determining, by the LPD and based on the second electrical signal, whether to deliver anti-tachycardia pacing to the heart from the LPD wherein determining whether to deliver anti-tachycardia pacing comprises determining, by the LPD and based on the second electrical signal, not to deliver anti-tachycardia pacing; wherein the method further comprises, in response to determining not to deliver anti-tachycardia pacing, transmitting, by the LPD and to the SICD, communication identifying the determination not to deliver anti-tachycardia pacing; and further comprising: receiving, by the SICD, the communication identifying the determination not to deliver anti-tachycardia pacing; and overturning, based on the received communication identifying the determination not to deliver anti-tachycardia pacing, the determination to deliver anti-tachyarrhythmia shock therapy to the patient.
