A little backstory: This is around 4 months ago, my last night working in the ER. I found these strips under my dresser when I was cleaning my room today. I had saved them to share on here and forgot. So the details of the case are little fuzzy as I don't remember them exactly but I'll do my best. Also in these ECGs some of them would not print correctly so its only a partial 12-lead.

So this is a 52 y/o female who was brought in by EMS with complaint of palpitations. When she arrives she doesn't appear to be in any acute stress. She looks a little worried, but doesn't appear to be pale, in pain, or diaphoretic.

We hook her up to the monitor and her pulse is anywhere from 50 to 170. It will go to a regular rhythm at a rate of 50-70 for about 30 seconds to a minute, sometimes less.... to a tachy rhythm and then it will slow itself down. We watched her do this for a good 10-15 minutes. She kept going back and forth.

Eventually the doc ordered a Brevibloc drip that stopped her from going into the tachy rhythm.

At first I thought it was Afib with RVR, but after watching how regular it was when it was at a slower rate... it seemed the irregularity was coming from intermittent PACs. Sorry couldn't provide more/better pictures. Still not sure what this was.

Looks like an atrial flutter, I agree with the computer.

There is some variable conduction, and it looks like it goes from a 2:1 to a 3:1 in the second ECG. One of the ECGs indeed shows NSR with a mess of PACs.

I wonder why esmolol versus diltiazem, or even plain metoprolol?

Couldn't tell you. This pt. came towards the end of my shift and it was my last night so I didn't get a chance to talk to the doc.

Any ideas on what would cause her to go from normal sinus to rapid atrial flutter and back again repeatedly?

Clearly she she some irritated atria but why does she go back and forth like that?

A PAC can certainly start a flutter circuit.

from what you described - wolff parkinson white syndrome? I can't really evaluate the ECG. Is there any way to zoom into the scanned file?

Again: http://en.ecgpedia.org/wiki/Main_Page might help.

Cheers!

Why WPW?

Normofrequency with frequent self-terminating episodes of irregular small-QRS-complex tachycardias sounds like an indication to check for WPW to me. Plus AF is afaik the most frequent rhythm distortion seen in Patients with WPW.

A 12-lead of the normal rhythm would be interesting to check for delta waves and short pr-interval.

Cheers!
