Abstract
An apparatus comprises a primary cardiac signal sensing circuit to sense a first cardiac signal, a secondary cardiac signal sensing to sense a second cardiac signal, and an arrhythmia detection circuit. The primary sensing circuit includes at least first and second implantable electrodes, and the secondary sensing circuit includes a third implantable electrode to deliver high-energy shock therapy. The arrhythmia detection circuit detects tachyarrhythmia using the primary sensing circuit, determines correspondence between events sensed with the primary sensing circuit and events sensed with the secondary sensing circuit, and deems whether a detected rhythm is indicative of noise or is indicative of an arrhythmia according to the determined correspondence.
