Pre- and post-atropine ECGs. What's the rhythm here? Concealed fascicular ectopy or AV block? If AV block, at what level and what degree? Thoughts?

Would love a second set of eyes on these ECGs. What is your interpretation? (22y-female, biventricular cmp+)

but a concealed posteroseptal AP. Retrograde conduction sometimes goes via the AVN, sometimes via the AP. The beats labeled "B" are PVCs. Looking at the other ECGs, they're multiform. Somehow a PVC follows a sinus beat, the sinus node gets suppressed,

and escape + couplet/triplet PVC clusters are triggered. Once automaticity shifts back to the sinus node, the loop breaks (examples on other ECGs). So, this reflects underlying SND. These are my opinions; what do you think?

How do you think we can explain the change in QRS morphology accompanying the PR interval prolongation in this ECG?

🟡 VT with 1:1 VA conduction 🟡 You have no AV dissociation but one to one association from the retrograde conduction in this ventricular tachycardia. 🧵 & 🔗

👇Typical Flutter: Quick tricuspid annulus map for diagnosis and ablation success assessment👇 👉 A very fast single-tip activation map of TV using the ablation catheter beautifully demonstrates the reentry circuit — in this case, a counterclockwise flutter around the tricuspid valve annulus. 👉 For success confirmation, pacing in the coronary sinus (CS) shows a collision of both activation wavefronts at the CTI line, without any breakthroughs across the block line. Beautiful maps by @StephanWinnik 🤩 🎥 This illustrative video was created in collaboration with @N_Trajkovska for Young #EPeeps 🙏 @Phiso_de @GNageler @MBraunEP @MoneebKhalaph @Cardioschool @PhilippLuc @chris_sohns @ecgandrhythmRoe @Ecgloverr @KostekMilan @JNJNews @EPWaveDoc @Mo_PedsEP @ArashArya_EP #CardioTwitter @YoungDgk @AGEP_DGK
