Managing cross therapy delivery in a multiple therapy implantable device

An apparatus comprising:

• a cardiac signal sensing circuit configured to sense an electrical cardiac signal from at least one of an atrium or ventricle of a heart of a subject, wherein the cardiac signal sensing circuit includes at least one sense amplifier circuit;
• a therapy circuit configured to provide electrical pacing therapy and electrical neural stimulation therapy to the subject;
• and
• a control circuit communicatively coupled to the cardiac signal sensing circuit and the therapy circuit and configured to:
• initiate delivery of electrical pacing therapy;
• initiate a blanking period in response to and in a time relationship to the delivery of electrical pacing therapy the at least one sense amplifier circuit is disabled during the blanking period;
• initiate delivery of the electrical neural stimulation therapy to the subject during the blanking period;
• and
• suspend delivery of neural stimulation therapy when the delivery of electrical pacing therapy is initiated within a specified time duration prior to the expiration of a ventricular escape interval.

• initiate delivery of the electrical pacing therapy;
• initiate a blanking period in response to and in a time relationship to the delivery of electrical pacing therapy, wherein the at least one sense amplifier circuit is disabled during the blanking period;
• initiate delivery of the electrical neural stimulation therapy to the subject during the blanking period;
• track a number of neural stimulation therapy pulses delivered over a specified time interval;
• and
• initiate additional delivery of neural stimulation therapy during at least one subsequent blanking period initiated by the control circuit to meet a specified neural stimulation therapy target dosing of electrical pulses delivered within a duration of time when the number of neural stimulation therapy pulses delivered is less than the specified neural stimulation therapy target dosing.
