Abstract

Methods and systems are provided to deliver a neural stimulation (NS) therapy utilizing a first NS operating configuration to assist anti-tachycardia pacing (ATP) therapy in response to a detected tachyarrhythmia. Before and after delivering of the NS therapy, characteristic values are measured for a rate-related physiologic characteristic (rate RPC) and a stability-related physiologic characteristic (stability RPC). The rate RPC is indicative of a frequency of a reentrant circuit within the tachyarrhythmia. The stability RPC is indicative of a hemodynamic stability of the reentrant circuit. The pre-NS and post-NS characteristic values for the rate and stability RPCs are analyzed to determine a rate RPC difference and a stability RPC difference. Different ATP therapies are delivered based on the type associated with the tachyarrhythmia, the rate RPC difference and the stability RPC difference.
