Systems and methods for safe delivery of electrical stimulation therapy
First Claim
1. A leadless cardiac pacemaker (LCP) comprising:
- a housing;
a plurality of electrodes for sensing electrical signals emanating from outside of the housing;
an energy storage module disposed within the housing;
a control module disposed within the housing and operatively coupled to the plurality of electrodes, wherein the control module is configured to;
receive electrical signals via two or more of the plurality of electrodes;
determine whether the received electrical signals are indicative of a command for the LCP to deliver anti-tachyarrhythmia pacing (ATP) therapy;
when the received electrical signals are indicative of a command for the LCP to deliver anti-tachyarrhythmia pacing (ATP) therapy, determine whether a triggered ATP therapy mode of the LCP is enabled;
when the received electrical signals are indicative of a command for the LCP to deliver ATP therapy and the triggered ATP therapy mode is enabled, deliver ATP therapy via two or more of the plurality of electrodes; and
when the received electrical signals are indicative of a command for the LCP to deliver therapy and the LCP is in a safe mode in which the triggered ATP therapy mode is not enabled, not delivering ATP therapy via two or more of the plurality of electrodes.

Abstract
Systems and methods for treating arrhythmias are disclosed. In one embodiment an LCP comprises a housing, a plurality of electrodes for sensing electrical signals emanating from outside of the housing, an energy storage module disposed within the housing, and a control module disposed within the housing and operatively coupled to the plurality of electrodes. The control module may be configured to receive electrical signals via two or more of the plurality of electrodes and determine if the received electrical signals are indicative of a command for the LCP to deliver ATP therapy. If the received electrical signals are indicative of a command for the LCP to deliver ATP therapy, the control module may additionally determine whether a triggered ATP therapy mode of the LCP is enabled. If the triggered ATP therapy mode is enabled, the control module may cause the LCP to deliver ATP therapy via the plurality of electrodes.
