Name the rhythm

[Ghettomedic351]

Is this lead II? If so there is evidence of an anterior hemiblock as well. The complex is down, lead III would be down as well, lending itself to a pathological left axis deviation which indicates an anterior hemiblock. As for the underlying rhythm... "it's lead II, so I have no clue." It'd be nice to call it a-fib, but without the benefit of a proper diagnostic ecg, it's tough to tell for sure. At first glance I actually thought I saw some p-waves, albeit inverted and differing in morphology. I initially thought it was a sinus rhythm with PAC's, and one (or two) really pissed off atrias. I realize this was a "teaching strip" but in the words of my very famous paramedic instructor... "What's wrong with the patient!"

the problem is medics reading way too much into simple Atrial Fib.

It looks like a heart block to me. Mobitz 1 perhaps? either that or A-Fib
