Abstract:
1. A method for determining an improved defibrillation shock energy (DFSE) for a patient, the method comprising: monitoring and tracking cardiac data of a patient by an implantable cardiac therapy device (ICTD); analyzing such cardiac data by the ICTD; automatically adjusting the DFSE from a first level predetermined to correspond to a first cardiac data value to a second level predetermined to correspond to a second, different, cardiac data value so that the ICTD may deliver a therapeutic shock at an energy level approximating an improved DFSE for the patient; wherein the cardiac data comprises data selected from a group consisting of cardiac rate, cardiac fibrillation rate, and duration since last therapeutic shock; wherein the duration since last therapeutic shock comprises a first DFSE for fibrillation immediately returning after a recent shock and a fibrillation returning after a long absence and further comprises a second DFSE for fibrillation returning between the two extremes; and wherein the first DFSE is higher than the second DFSE.
