1. A method for controlling cardiac ventricular tachyarrhythmias using an implanted medical device, the method comprising the implanted medical device:

  • acquiring a pressure signal representative of coronary venous pressure (CVP) from a pressure sensor implanted within a coronary vein of the patient, and deriving a CVP index based on the pressure signal;

    acquiring a rate signal indicative of the patient'"'"'s cardiac rate from an implanted rate sensor;

    detecting an onset of a ventricular tachyarrythmia (VT) episode based on the rate signal;

    monitoring the rate signal and the CVP index for an episode monitoring period; and

    responsive to the rate signal indicating a sustained tachycardia episode during the episode monitoring period, selectively withholding anti-tachycardia therapy and extending the episode monitoring period based on the CVP index.
