Anatomic ablation of the left posterior fascicle successfully terminated posterior fascicular ventricular tachycardia in a 24-year-old male, with post-tachycardia T-wave inversions indicating cardiac memory.
Case Report (n=1)
This case highlights the diagnosis and successful ablation of posterior fascicular ventricular tachycardia, with post-tachycardia T-wave inversions attributed to cardiac memory.
TWIs after fascicular VT may reflect cardiac memory; this single case extends the association but leaves prevalence and implications open.
We present a case of a 24-year-old male with palpitations and a wide complex tachycardia. Baseline electrocardiogram (ECG) after termination of tachycardia demonstrates a normal rhythm but with inferior/anterolateral T-wave inversions (TWIs). Electrophysiologic study confirmed the diagnosis of posterior fascicular ventricular tachycardia successfully terminated by anatomic ablation of the left posterior fascicle. TWIs on the patient's baseline ECG were consistent with cardiac memory.

Siroky et al. (2020) conducted a case report in Wide complex tachycardia (n=1). Anatomic ablation of the left posterior fascicle was evaluated on Termination of tachycardia. Anatomic ablation of the left posterior fascicle successfully terminated posterior fascicular ventricular tachycardia in a 24-year-old male, with post-tachycardia T-wave inversions indicating cardiac memory.
