Name the rhythm

Not sure if I'm looking too much into it or not but there seems to be more to this than first meets the eye. Measure out the R-R intervals for the groups.

A-fib @ 55-130

Well I was going to name it Colin, but I think I will agree with AF.

Now I am no master of ECG's but here's what I see:

- Irregulat R-R interval

- Dropped P waves

- Runs of what looks like A Fib or consistent artifact

- Irregular ST segment height and length

Could be a block or some sort of electrolyte imbalance ... I'm not really sure

Its difficult to see from this strip as the quality is not great. Regardless I would like to see more leads. From this I would think either A-fib or artifact.

Additionally, maybe mobitz type 1 A/V block. More strip to compare baseline would be warranted to try to rule out artifact.

Could be from a number of reasons. Any more info on the patient, specifically history and meds?

Looks like afib. Got a 12 lead?

[fiznat]

Yeah I think I'm going to go with a-fib as well.

I thought for a second that the rhythm looked regularly irregular, but it isn't once you march it out. A longer strip or a 12 lead would definitely seal the deal.

I definitely think something with less artifact would be helpful. I was initially thinking afib, but they also seem to be coming in groups of 4 (albeit on a very limited strip). Maybe a block that we just can't see the p waves because they are burried in the artifact.

Fib-flutter....In the begining of the strip it looks like flutter waves at a rate of over 300 bpm, with variable block...later the atrial activity becomes less apparent, perhaps fibrillation. A better quality tracing, 12 leads even better would be helpful.

This is all I have. It is part of a package that my gf (in Primary Care Paramedic school) got for ECG interpretation teaching. They are calling it A-Fib.... I disagree. There is no 12-lead, no other leads, no history. What you see is what is given.

I don't call it A-Fib.

Every block of 4 beats the first 3 have identical R-R to each other then the fourth is delayed, perhaps an escape beat.

I don't know what to call it but it isn't A-Fib
