[Surprising mechanism of highly symptomatic tachycardia in a young patient : Diagnosis and treatment]. / Überraschender Pathomechanismus hochsymptomatischer Tachykardien bei einem jugendlichen Patienten : Diagnostik und Therapie.

ABSTRACT

The diagnosis of paroxysmal tachycardia can be challenging in clinical practice because even with a typical patient history including palpitations, tachycardia, and an on/off phenomenon, 24 h Holter monitoring frequently fails to document the tachycardia. After unsuccessful 24 h Holter monitoring, we managed to document a very fast wide QRS complex tachycardia in a young patient by a mobile portable event monitor. Subsequent invasive electrophysiologic diagnostics followed by catheter ablation clarified the tachycardia mechanism and led to permanent elimination of the tachycardia.
