Idiopathic Ventricular Arrhythmias Originating From the Infundibular Muscles: Prevalence, Electrocardiographic and Electrophysiological Characteristics, and Outcome of Catheter Ablation [Original Articles]
Conclusions:
Idiopathic VAs originating from the IFMs are rare (PB>SB). Catheter ablation of these IFMs VAs was challenging, requiring a large amount of the radiofrequency energy delivery for a successful ablation with a relatively high recurrence rate.
