SYSTEMS AND METHODS FOR INCREASING PACING OUTPUT AFTER EXTERNAL HIGH-ENERGY ELECTRICAL SHOCK
First Claim
1. A medical device comprising:
- a shock detection circuit; and
a pacing output circuit in communication with the shock detection circuit, the pacing output circuit configured to generate pacing pulses, the pacing output circuit configured to increase the amplitude of the pacing pulses and/or increase the pulse width of the pacing pulses in response to the shock detection circuit detecting a defibrillation or cardioversion shock delivered by an external device.
