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🤪 🔗 jacc.org/doi/10.1016/j.jacca…

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

What upsets me is the same pattern of onset. It’s slightly irregular, and I can’t see clear capture or fusion beats.

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

I didn't know it existed, I learned a new PMT mechanism: Pacemaker‐mediated tachycardia in the absence of retrograde ventriculoatrial conduction. 2018, Journal of Cardiovascular Electrophysiology, Xavier Viñolas. @swahz7788 @Willis_Kwandou @JimLascivious @SparkyDeviceRN

Rhythm? 90+ years old, chronic FA. 1st ECG 25 mm/sec and 2nd 50 mm/sec.

It was AT. The ECG below is after cardioversion. The history regarding chronic AF was incorrect; however, this was the history I was given. I think the alternating LAFB and LPFB during AT are due to tachycardia-dependent, functional block of the fascicles.

And ECG now (8 hours after 1st ECG)

The case of an 84-year-old woman who took hydroxychloroquine (HCQ) for several years for cutaneous lupus and later developed HCQ-induced cardiomyopathy highlights a rare side effect of prolonged HCQ use. f.mtr.cool/eufdehioab

Same patient. ECG #1 at presentation, #2 after cardioversion, and #3 few days later. Known to have abnormal fat deposition in RV and scarring in septum in CMR done before.
