My first post on 2:1 atrial flutter turned out to be one of my most popular and successful contributions to the FOAM world over the past few years, so I thought I’d go ahead and build on that a bit. Collected here are 50 different examples of rapid atrial flutter. Some are easy, most are a bit tricky, and a few a near-impossible; but they’re all atrial flutter. So, without further ado, get to it and start seeing atrial flutter.
EDIT (2013.11.21): Thanks to the keen eyes of EKG mavens David Richley and Ken Grauer, a couple of possible errors were spotted in the collection. #1134 is definitely NOT atrial flutter but rather AVNRT, though the patient was definitively in atrial flutter only 1 hour prior to that tracing. Also I will be taking another look at #0585, 0737, and 0808 to make sure those weren’t incorrectly included as well. A formal update and correction will be out this weekend.
