| 1. A system comprising:
a wireless electrostimulation electrode assembly comprising electrostimulation electrodes, the wireless electrostimulation
electrode assembly sized and shaped for implant at a myocardial site using a percutaneous, transluminal, catheter delivery
system, the wireless electrostimulation electrode assembly configured to receive electromagnetic energy from a source outside
the myocardium;
a source of electromagnetic energy sized and shaped for placement within a person's body outside the myocardium and separate
and detached from the wireless electrostimulation electrode assembly, the source of electromagnetic energy including or conductively
coupled to sensing electrodes that are configured to sense a locally measured electrogram to time an electrostimulation of
the heart by wirelessly sending a command to the wireless electrostimulation electrode assembly to electrostimulate the myocardium;
wherein the source of electromagnetic energy comprises an electronic control circuit, a transmit circuit, a battery, and an
antenna; and
wherein the locally measured electrogram is sensed by the sensing electrodes included in or conductively coupled to the source
of electromagnetic energy.
