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 LPDwherein 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.
