ABSTRACT:
A device-implemented method detects and treats abnormal (i.e., pathologic) tachycardias experienced by a patient with an implanted automatic defibrillator. The defibrillator has the capability to distinguish pathologic tachycardia from physiologic tachycardia by the application of predetermined distinction criteria programmed into it. Changes in a physiologic parameter of the patient which signify a physiologic basis for increase or decrease of the patient's heart rate are detected, and in response, the distinction criteria are modified to enhance the capability of the defibrillator to make the distinction between pathologic and physiologic tachycardia when this change in circumstances that would otherwise tend to obscure the distinction is factored in. In one method, the parameter under detection is patient activity, and the distinction criteria include a threshold heart rate above which the patient is presumed to be experiencing a pathologic tachycardia. The threshold rate is shifted up or down depending on whether the detected change is indicative of an increase or a decrease, respectively, of the patient's heart rate.
