Just published: a rare ECG case of dual atrioventricular nodal non-reentrant tachycardia (DAVNNT) in @JACCJournals! #JACCCaseReports #EPeeps #ECG

I somehow managed to delete the original post. Sorry for the mess🤪

[Kaspar L. @kaspar_86]

@swahz7788 @Frances98392343 Yep

[Kaspar L. @kaspar_86]

@Frances98392343 Do you have other theory?

[Kaspar L. @kaspar_86]

@Frances98392343 Likely AT

[Kaspar L. @kaspar_86]

@Frances98392343 In the blue box there is temporary slowing near to MTR likely due to PVC and there SAV is shorter than native conduction. Not sure if it's hysteresis. Anything in the ventricle that is before or after is less than 460 ms.

@RobertHermanMD @smithECGBlog @PendellM @ecgandrhythmRoe @ecgrhythms @TheECGMedic @DrparrayMD @DrRazi4 @EM_RESUS @AndrewACNP1 @tbouthillet LAD for me

[Kaspar L. @kaspar_86]

@syamkumarmd FP and SP conduction likely. Thought about (post-TAVR) IDC, but seems unlikely since no BBB.

[Kaspar L. @kaspar_86]

@doctor_roig @JACCJournals @ekgdx @KostekMilan @smithECGBlog @CardioBornan @AThomazAndrade @ecgandrhythmRoe Very nice, congrats!

[Kaspar L. @kaspar_86]

@Frances98392343 Ap during PVC and then pacing on T. NSVT with 2:1 VA conduction.

[Kaspar L. @kaspar_86]

@KostekMilan True. I missed that.

[Kaspar L. @kaspar_86]

Atypical aberration due to abnormal baseline ECG or NSVT during flutter? 3rd ECG is older.

[Kaspar L. @kaspar_86]

@Frances98392343 It was AVRT with retrograde conducting AP 🤷😂

[Kaspar L. @kaspar_86]

🙂

@melhamriti @ALFIEEP1 @hospitalposadas +1

[Kaspar L. @kaspar_86]

@Frances98392343 Is the rate smoothing programmed on?

[Kaspar L. @kaspar_86]

@Frances98392343 I do not know why the AS marker is missing there, but I agree that FFRW oversensing causes SAV. Likely PVC from LV seen late by RV lead and early by atrial lead?

[Kaspar L. @kaspar_86]

@Frances98392343 3rd ECG taken 6 months later. But in between, it looked pretty much alike.

[Kaspar L. @kaspar_86]

Three ECGs from a man in his 60s. No additional information available. Thoughts?
