Device interrogation revealed the presence of pacemaker-mediated tachycardia (PMT), but since the episode trigger had been programmed off, it was not possible to determine when they occurred, how long they lasted, or their rate.

Given the patient's severe left ventricular systolic dysfunction and the absence of any overt alternative explanation, the PMT likely triggered the syncope preceding the car accident.
