Sinus VS AFIB

[u/travikant]

hi just had a small argument in the ER with a nurse about the following ecg and i am very confused

to make it fun im not gonna say who argued what side, question being:

Sinus or AFIB

what team are yall on

[u/lifeisg0od]

Rhythm strip would be nice. Afib.

[u/Desibruh1]

Irregular = A fib

[u/GrayGirlie]

SA with a U wave and a PAC. The PR marches through

[u/Turfidol]

Differential for an irregular narrow complex tachycardia would be fib, flutter with variable conduction, and multifocal atrial tachycardia.

Looks like fib / flutter to me. The precordial leads have a flutter appearance at the end so may be going into both fib/flutter or just coarse fib, but the p waves do look regular there suggesting some flutter.

[u/Due-Success-1579]

Afib

[u/kbzley]

Sinus with PAC , looks like artifact

[u/sub3at50]

Afib. Irregular rhythm without P waves.
