On the ECG, the leads reflecting activity in the RA appear more organized compared to the others.

EP fellows, check out the anatomy of the tricuspid valve, Halo, and CS catheter in a patient with TVR in LAO #Epeeps #CardioTwitter #Electrophysiology

@andrearossi3112 @javadm20 @sozi81 @MRazminia @ArashArya_EP It was left anterolateral

@MASA02460147 @javadm20 @ArashArya_EP @ShamlooSepehri @syamkumarmd I couldn’t rule out JT or NF ORT, but the arrhythmia was easily resolved with slow pathway ablation.

@javadm20 @ArashArya_EP @ShamlooSepehri @syamkumarmd I couldn’t rule out junctional tachycardia (JT), but the arrhythmia was easily resolved with slow pathway ablation.

Attention, cardio enthusiasts and EP fellows! Check out this fascinating EP tracing captured during the ablation of a WPW syndrome case. Stay tuned for the answer in the next slide! #EPeeps #Cardiology #wpw Case 650

@javadm20 Induce AFib with rapid A pacing, narrower QRS will be suggestive for AV conduction

@Hapa_EP @ALFIEEP1 @Arritmias_HRC @Toaster_Pastry @PennEPFellows @EPWaveDoc @Koichi16423232 @KTamirisaMD @sumitvermaep @adribaran @rdschaller I tailor each case individually. With this nice early signal, I will perform focal ablation with minimal side burns!

@Matthew03162300 I'm curious as well! but I don't have access to it.

Case 646 Atypical flutter. 3D mapping revealed isthmus and lines of block, both functional and from previous RF ablation. With accurate mapping, the ablation procedure was expected to be straightforward.

@syamkumarmd Great

@syamkumarmd @OJiravsky Agree that midseptal APs carry much higher risk.

@syamkumarmd There are reports of SCD in cases of intermittent preexcitation, based on this evidence ESC guidelines suggest EPS+/-ablation for all such cases.

@FergieLosiniec1 @Johncfmiami @s_timilsina @Mapbastian @mhshospital @DanielBenhayon How did you pace both A and V at the same time? What is the advantage?
