Key result
Induced sustained ventricular tachycardia in a post-MI patient exhibited three forms with variable termination patterns showing no change, decrease, or increase in cycle length.
Induced sustained VT in a post-MI patient can exhibit variable spontaneous termination patterns with differing cycle length behaviors.

Variable VT termination patterns in post-MI cases may refine EP mapping; leaves open mechanistic and therapeutic implications.
A 43-year-old man, with repeated episodes of postmyocardial infarction monomorphic VT, had three forms of induced sustained VT in the electrophysiology lab. The three forms of VT had variable termination patterns with no change, decrease, or increase of cycle length.
