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.

An implantable medical device can include an integrated circuit comprising an electrostatic discharge (ESD) protection circuit. The ESD protection circuit can include an active circuit, a first passive circuit, and a second passive circuit. For example, at least one of the first or second passive circuits can include an array of capacitors in a series configuration, a parallel configuration, or a combination of series and parallel configurations. The first and second passive circuits can be configured to establish a specified time constant, and, in response to an applied ESD, the first and second passive circuits can provide a control signal to active circuit to switch the active circuit from a substantially non-conductive mode to a substantially conductive mode.

Systems and methods for communicating between medical devices. In one example, an implantable medical device comprising may comprise one or more electrodes and a controller coupled to the electrodes. The controller may be configured to receive a first communication pulse at a first communication pulse time and a second communication pulse at a second communication pulse time via the one or more electrodes. The controller may further be configured to identify one of three or more symbols based at least in part on the time difference between the first communication pulse time and the second communication pulse time.

Systems and methods for communicating between medical devices. In one example, an implantable medical device comprises a communication module configured to receive commands from other medical devices, wherein the commands include a relative address and a command payload; a memory unit that stores a relative address and a unique identifier of the implantable medical device; a processing module coupled to the communication module and the memory unit, the processing module configured to: determine whether the relative address of a received command matches the relative address stored in the memory unit of the implantable medical device; if the relative address of the received command matches the relative address stored in the memory unit of the implantable medical device, execute the received command; and if the relative address of the received command does not match the relative address stored in the memory unit of the implantable medical device, ignore the received command.

Methods and devices for testing and configuring implantable medical device systems. A first medical device and a second medical device communicate with one another using test signals configured to provide data related to the quality of the communication signal to facilitate optimization of the communication approach. Some methods may be performed during surgery to implant one of the medical devices to ensure adequate communication availability.
