Idioventricular rhythm is a common "reperfusion arrhythmia." Our electrophysiologist, Rehan Karim, states he has ablated AVNR"T" ("T" because it is not tachycardia) in a 90 year old, and that he has seen rate-related BBB at very slow rates. In fact, there may be less than 1 mm of concordant ST depression in lead V3.

Flecainide : This is a potentially dangerous Na channel blocker which can cause ventricular dysrhythmias including ventricular fibrillation. Is this patient a candidate for cardioversion or ablation? ( If ablation is contemplated — definitive diagnosis will be made at EP study. ( How to Distinguish Between AFlutter vs ATach?

But adenosine only lasts for seconds, and if the dysrhythmia recurs, then the adenosine is gone. Prevent the initiation of the dysrhythmia -- this can be done with a beta blocker by prenenting PACS 2. There is no need to immediately refer today’s patient to EP for ablation. Smith: should we give adenosine again?

The patient was found to have a "concealed" posteroseptal pathway (WPW without delta waves) confirmed to have SVT at EP study and was ablated. Here is the Electrophysilogist's note: "Only 1 pathway attachment could be ablated, the second one deep within the CS could not be ablated with high power.
