ABSTRACT:
A low-power cardiac pacer and method includes an automatic capture threshold determination system wherein the minimum pulse energy required to reliably stimulate contractions of a patient's heart is periodically determined. The energy level of pacing pulses generated by the pacer is automatically set in accordance with the determined capture threshold level to reduce battery current drain and thereby extend the pacer's useful life.
