What do you think is the rhythm?
🐦 ur reply if none of the 4 choices

AF-atrial fibrillation
ST-sinus tachycardia
VT-ventricular tachycardia
AFL/AT-atrial flutter/ atrial tachycardia
This is the ff-up ECG. This is not SR. The 🔑 to rhythm dx is in the PRI (long lead). You need a caliper to 👀 the PR difference. If you have 🦅👀 the extra P can be 👀. So, the ECG case can be explained with 1 reason.

Tnx for all the replies. This is indeed so tricky. The atrial rate seemed slow to allow 1:1 conduction. Addt HR trend & ECG to highlight the slower rate. ImageImage
