1. An implantable cardiac device comprising:
a diaphragm lead configured to be implanted on or adjacent a diaphragm;
one or more cardiac leads configured to be implanted in or on a heart; and
an electronics component having an electrical circuit structure configured to electrically couple with the diaphragm lead and the one or more cardiac leads, the electrical circuit structure configured to:
detect a cardiac event in a cardiac cycle based on a signal sensed through the one or more cardiac leads, and
deliver asymptomatic electrical stimulation therapy to the diaphragm through the diaphragm lead in response to the cardiac event.
