1. An apparatus comprising:

  • a primary cardiac signal sensing circuit configured to sense at least a first cardiac signal, the primary cardiac signal sensing circuit including or configured to be coupled to at least first and second implantable electrodes;

    at least one secondary cardiac signal sensing circuit configured to sense at least a second cardiac signal, the secondary cardiac signal sensing circuit including or configured to be coupled to at least a third implantable electrode, different from the first and second electrode, configured to deliver high-energy shock therapy; and

    an arrhythmia detection circuit communicatively coupled to the primary and secondary cardiac signal sensing circuits, wherein the arrhythmia detection circuit is configured to;

    detect tachyarrhythmia using the primary sensing circuit;

    determine correspondence between events sensed with the primary sensing circuit and events sensed with the secondary sensing circuit; and

    deem whether a detected rhythm is indicative of noise or is indicative of an arrhythmia according to the determined correspondence.
