Distinguishing supraventricular tachycardias (SVTs) from ventricular tachycardias (VTs) has obvious importance because treatments are very different. This chapter…

Catheter Ablation of Superoparaseptal (Anteroseptal) and Midseptal Accessory Pathways

Key Points Diagnosis of superoparaseptal ( anteroseptal ) and midseptal accessory pathways (APs) is made on the basis of an electrocardiographic pattern (if overt preexcitation is present) and evidence of midseptal/anteroseptal AP insertions during intracardiac mapping studies. Orthodromic supraventricular tachycardia…
