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

@Frances98392343 @Ecgloverr @lila_enis @FibrilloFlutter @ecgandrhythmRoe The previous/first ECG showing AV dissociation and fusion beats suggests VT. This ECG, which is very similar but slower and has QRS complexes with different morphology (there also seems to be av dissociation). Do you think it could be pleomorphic VT?

25 ms/10mV. Is there LVH or not?

Universal agreement on how to assess for LVH on ECG is lacking. How can there be agreement? — when more than 50 sets of criteria for LVH have been published in the literature. Practically speaking — none of these 50-plus criteria are optimally accurate. All suffer from imperfect sensitivity, which is no better than 55% by even the best of electrocardiographers. This means that up to half of the time when LV (Left Ventricular) thickening or LV chamber enlargement is present beyond the normal adult range — that it will not be detectable based on ECG assessment. @ekgpress ecg-interpretation.blogspot.…

Pacemaker bigeminy is not an uncommon electrocardiographic finding in device clinics. However, such a pattern mandates the differentiation of important possible diagnostic considerations such as premature atrial contractions, oversensing the T wave or the QRS complex, dual AV nodal physiology, and retrograde atrial depolarization.

Final pdf of our article in JACC Advances is finally out. Hyperacute T Waves Are Specific for OMI, Even Without Diagnostic STE First quantitative definition of HATW: they have 1) large AUC relative to QRS amplitude and 2) increased symmetry. jacc.org/doi/epdf/10.1016/j.…
