59 year old lady with permanent DDD pacemaker for AV nodal disease. The settings include escape pacing rate 50/min, maximal rate 80/min, sensed AV interval 020”, pacing AV interval 0.24” and PVARP 0.36”; there is no rate hysteresis. The sensitivity was 1.0 mV. She reported recurrent dizziness, pre-syncope, dyspnœa and fatigue, but the pacemaker function was normal when formally tested.
