1. A method of controlling VT and VF detection in an implantable medical device, the method comprising:

  • sensing R-waves in a ventricular EGM signal;

    monitoring in real time on an event-by-event basis a plurality of characteristics that indicate T-wave oversensing; and

    withholding detection of a VT or VF in response to the characteristics indicating presence of oversensed T-waves among the sensed R-waves.
