<p>A method of detecting the status of the battery of an implantable heart stimulator comprises the steps of measuring the impedance of the battery, detecting an increased value of the measured impedance, determining an impedance based value of the remaining capacity of the battery from the detected impedance increase, combined with the steps of measuring the total charge depleted from the battery, and determining a charge depletion based value of the remaining capacity of the battery. A battery status detecting circuit for an implantable heart stimulator includes a first measurement means (12) for measuring the impedance of the battery (6), a detection means (14) for detecting an increased value of the measured impedance, a first determination means (16) for determining an impedance based value of the remaining capacity of the battery from the detected impedance increase. A second measurement means (22) is provided for measuring the total charge depleted from the battery, and a second determination means (24) is provided for determining a charge depletion based value of the remainig battery capacity.</p> |
