1. A medical device system, comprising:
a first device comprising:
a housing;
a first housing-based electrode;
a second housing-based electrode;
sensing circuitry enclosed by the housing and configured to sense via a sensing electrode vector between the first housing-based electrode and the second housing-based electrode a P-wave attendant to an atrial activation of a patient's heart; and
a signal generator coupled to at least one of the first housing-based electrode and the second housing-based electrode for transmitting a communication signal via one or both of the first housing-based electrode and the second housing-based electrode, the signal generator being configured to, in response to the sensing circuitry sensing the P-wave, transmit the communication signal in timed relation to the P-wave sensed by the sensing circuitry; and
a second device comprising:
a receiver configured to receive the transmitted communication signal;
a power source comprising at least one battery; and
a pacing pulse generator configured to:
receive power from the at least one battery for generating a pacing pulse; and
deliver the pacing pulse in response to the receiver receiving the transmitted communication signal.
