1. A method comprising:
determining, by processing circuity of an implantable medical device implanted in a patient, that a triggering event has occurred based on statuses for a set of physiological parameters associated with the patient, the physiological parameters indicative of the patient engaging in a patient initiated physical activity;
generating, by trigger circuitry of the implantable medical device, a trigger output signal in response to the determination that the triggering event has occurred;
wirelessly transmitting, by a communication circuitry of the implantable medical device, the trigger output signal to a pressure sensing device implanted in a vessel of the patient;
triggering, based on receiving the trigger output signal at a communication circuitry of the pressure sensing device, the pressure sensing device to sense a cardiovascular pressure of the patient; and
transmitting, by the communication circuitry of the pressure sensing device, a wireless signal to the implantable medical device, the wireless signal comprising data corresponding to the sensed cardiovascular pressure of the patient; and
wherein determining that the triggering event has occurred based on at least one status for the set of physiological parameters associated with the patient further comprises:
determining, by a timer in the implantable medical device, if a minimum amount of time has elapsed since a last triggering event has occurred, and
generating a trigger output signal only if the minimum amount of time has elapsed and only then in response to the determination that the triggering event has occurred based on the statuses for the set of physiological parameters associated with the patient.
