[Syncope-Related Gallavardin Tachycardia Detected by an Implantable Monitor in an Elderly Patient : Ablative Management].

We report the case of a 75-year-old female patient who was evaluated for an exertional syncope, revealing an infundibular ventricular tachycardia. The diagnosis was made possible by the implantation of a loop recorder, which detected frequent episodes of non-sustained ventricular tachycardia. Radiofrequency ablation guided by a three-dimensional mapping system led to the complete suppression of the arrhythmias. This case highlights the value of implantable monitoring tools in the etiological diagnosis of syncope, the importance of obtaining a 12-lead ECG during the arrhythmia to determine its origin, and the role of three-dimensional mapping systems in the diagnosis and treatment of idiopathic ventricular arrhythmias.
