Summary:A cardiac stimulator is provided for detecting and treating ventricular tachyarrhythmias of a patient's heart. The stimulator includes means for selectively dividing the heart rate continuum into regions including at least two classes of tachycardia (TACH-1, TACH-2, TACH-3), contiguous to each other and of progressively higher heart rate ranges, the lowest and highest of the tachycardia classes being bounded respectively by a sinus rate region (SINUS) and a fibrillation region (FIB) of the continuum. Means are provided for selectively adjusting the boundaries between the tachycardia classes and between the lowest and highest of those classes and the respective sinus rate and fibrillation regions, to correspondingly adjust the rate ranges of the classes in a desired manner. Cardiac events are selectively detected anywhere within the continuum and a distinction made between normal and abnormal tachycardias among the detected events. A detected abnormal tachycardia is then treated with any of a multiplicity of therapy regimens of differing degrees of aggressiveness, toward terminating the detected tachycardia.
