MY Approach to the Rhythm in Figure-1: As per ECG Blog #185 — I favor the P s, Q s, 3 R Approach for interpretation of the cardiac rhythm — beginning with whichever of these 5 KEY Parameters is easiest to assess for the tracing in front of me: At least in the single lead II rhythm strip seen in Figure-1 — The Q RS complex appears to be narrow.

Here are 4 more ECGs recorded over the ensuing hours: Another irregular AIVR Back to sinus rhythm This is a normal regular AIVR Another normal regular AIVR On that first ECG, I was not entirely certain, since I have never seen nor heard of irregular AIVR, nor can I find a report of it in the literature. All troponins were negative.
