Abstract
An improved implantable pacemaker/defibrillator device in which a first and relatively simplistic technique is employed to detect an abnormal heart rhythm and a second more precise algorithm is utilized for the more difficult problem of confirming the arrythmia. Since the complex, higher power consuming device is utilized only for confirmation, overall power consumption is minimized. Optionally, the precise algorithm may be utilized periodically to adjust the sensitivity of the detection circuitry.
