Population

A 74-year-old man with a dual-chamber implantable cardioverter defibrillator implanted 3 years prior experiencing multiple ventricular tachycardias (n=1).

Intervention

Interruption of pacemaker-mediated tachycardia (PMT) by atrial undersensing or tachycardia termination algorithm.

Outcome

Initiation of ventricular tachycardia (VT) by a short-long-short ventricular sequence following PMT termination.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

This case highlights a proarrhythmic mechanism where the termination of pacemaker-mediated tachycardia can induce ventricular tachycardia via a short-long-short sequence.
