Differential effective refractory period as a useful marker of multiple accessory pathways

Accessory pathway (AP) ablation failure may be related to multiple pathways which go unrecognized at the time of electrophysiology study. We present a patient who had two adjacent APs based on different preexcitation patterns as well as effective refractory periods (ERPs) which have not been previou...

description Accessory pathway (AP) ablation failure may be related to multiple pathways which go unrecognized at the time of electrophysiology study. We present a patient who had two adjacent APs based on different preexcitation patterns as well as effective refractory periods (ERPs) which have not been previously described. Apart from leading to recurrent supraventricular tachycardia (SVT), multiple pathways are important to recognize as they more frequently predispose to malignant atrial arrhythmias.
