Classification: A61N

Abstract:
1. An implantable cardiac rhythm management device, comprising: a pacing circuit configured to deliver atrial pacing pulses and ventricular pacing pulses; a tachyarrhythmia detection and classification circuit configured to detect a tachyarrhythmia and classify the detected tachyarrhythmia; and an anti-tachycardia pacing (ATP) control circuit coupled to the pacing circuit and the tachyarrhythmia detection and classification circuit, the ATP control circuit configured to control delivery of the atrial pacing pulses and the ventricular pacing pulses according to a plurality of ATP modes including a synchronized atrio-ventricular ATP (synchronized AV-ATP) mode during which the atrial pacing pulses and the ventricular pacing pulses are delivered synchronously, the ATP control circuit including an ATP mode selector configured to select an ATP mode from the plurality of ATP modes using one or more specified ATP mode selection criteria and the classification of the detected tachyarrhythmia, wherein the tachyarrhythmia detection and classification circuit includes a correlation analyzer configured to produce a correlation coefficient representative of a correlation between a tachyarrhythmic waveform sensed during the detected tachyarrhythmia and a template waveform, and the ATP mode selector is configured to select the synchronized AV-ATP mode from the plurality of ATP modes using the correlation coefficient.
