CNA - my first case CNA with carotid node stimulation. It wasn’t difficult for first time. What do you think colleges?

Pasquale Santangeli Jeffrey Winterfield John Silberbauer Doesn't the large confluent air space imply that the adhesions were not significant or do you think that instillation of air helped to separate loose adhesions?

Roderick Tung Jeffrey Winterfield John Silberbauer Anterior/inferior RV the space was open but the entire antero-lateral LV area was inaccessible (and couldn’t map it). Luckily we had to target only an inferior LV epicardial substrate.

#EPeeps I'd very interesting in your thought on this one: young female with exertion related VT terminated in A&E by verapamil. Pic: VT initiated from atrium, deca along post fascicle. No visible P1. After this point VT not inducible (bump?). Opening thread below:

A very interesting statement. What about statistics in medicine?

Picked this maneuver up from John Miller this weekend! Lifelong learning from those with more experience is the beautiful thing about EP. Late PAC resets AVNRT from CS 1,2 but not 9,10. Proof of left-sided input after failed right sided slow pathway RF. Stavros Stavrakis et al👇
