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🤪

@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.
@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?
