I see the following: Although there is no long lead rhythm strip — we can see that the rhythm is AFib with a controlled ventricular response ( ie, irregularly irregular rhythm without P waves — and with a heart rate between ~70-110/minute ). Regarding Intervals: There is no PR interval ( since the rhythm is AFib ).

MY THOUGHTS on ECG #1: My initial impression on looking at the ECG in Figure-1 — was that the rhythm was either rapid AFib in a patient with WPW — or — PMVT ( P oly M orphic VT ). The reason I initially thought the underlying rhythm was AFib — is that no atrial activity is seen in any lead and the rhythm “looks” irregular. See text ).

The QRS is wide in B — but the rhythm is irregularly irregular with no sinus P waves — so this most probably represents rapid AFib with an atypical RBBB/LPHB morphology. We now see that QRS morphology in lead II during sinus rhythm is similar to the QRS morphology in lead II during rapid AFib (beats #1-5 in lead II in A). 8] Liu, E.,
