1. A method for determining physiological status of a patient, said method comprising:
- detecting the activity level of the patient using one or more piezoelectric accelerometers to determine whether the patient is asleep;
recording a separate intramyocardial electrogram for each of a right ventricle and a left ventricle of a heart of the patient in response to signals from the one or more piezoelectric accelerometers when the patient is asleep;
measuring the amplitude and change in voltage over time of the intramyocardial electrograms;
averaging the amplitude and change in voltage over time measurements for the right ventricle and left ventricle; and
transmitting the averaged measurements to a receiver for communication to an intended recipient.

Abstract
A system and method determining physiological status of a patient. A determination is made whether the patient is sleeping. The amplitude and change in voltage over time of any intramyocardial electrogram is measured for a right ventricle and a left ventricle of a heart of the patient for a predefined number of heartbeats at a specified time interval in response to determining the patient is asleep. The measurements are averaged for the right ventricle and left ventricle. The averaged measurements are transmitted to a receiver for communication to an intended recipient.
