Invasive electrophysiology Glass of water or ablation? – episodes of malignant atrial tachyarrhythmias during swimming in a lake in a woman with overt Wolff-Parkinson-White syndrome and benign palpitations for several decades of life

Abstract

We present a case of a 41 year old woman with overt Wolff-Parkinson-White syndrome (WPW) and benign palpitations for over four decades of life who suffered from a malignant atrial tachyarrhythmias (typical atrial flutter concomitant with left atrial fibrillation) during swimming in a lake. Loading dose of amiodarone increased frequency of attacks of sustained AVRT. In spite of treatment with amiodarone, effective refractory period of accessory pathway was still short. After ablation of accessory pathway, during five years of follow-up, there was no arrhytmia recureence.
