A patient who received a patient‐activated pacemaker system for termination of paroxysmal, drug‐resistant, ventricular tachycardia is described. During the pre‐implant invasive electrophysiological (EP) study and the three post‐implant non‐invasive EP studies, tachycardias were easily and reproducibly terminated by two stimuli using the interval scanning mode. On the fourth day post‐implant, this pacing mode no longer terminated tachycardia at rest. A new pacing mode using more stimuli was then found to terminate the tachycardia reproducibly under various Physiological conditions. This case report demonstrates a spontaneous change in the tachycardia terminating window and the usefulness of versatility in antitachycardia pacemaker systems.
