SYSTEMS AND METHODS FOR MANAGING TIERED TACHYCARDIA THERAPY

Systems and methods are provided for managing tiered tachycardia therapy. The systems and methods measure a cardiac feature of interest (FOI) from a cardiac electrical signal of a heart sensed from at least one electrode of a leadless cardiac pacemaker (LPM). The systems and methods detect when the cardiac FOI satisfies an arrhythmia criteria, and deliver anti-tachycardia pacing (ATP) to the heart using the at least one electrode of the LPM when the cardiac FOI satisfies the arrhythmia criteria. The systems and methods deliver a series of arrhythmia emulating (AE) pulses configured to emulate a cardiac arrhythmia to the heart using the at least one electrode of the LPM if the FOI in cardiac signals measured subsequent to the delivery of the ATP therapy satisfy the arrhythmia criteria.
