BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. Colchicine did not prevent atrial arrhythmia recurrence at 2 weeks (31% versus 32%; hazard ratio [HR], 0.98 [95% CI, 0.59–1.61];P=0.92) Circulation: Arrhythmia and Electrophysiology, Ahead of Print. 2.02];P=0.89). 1.99];P=0.55).CONCLUSIONS:Colchicine

To me, it was clearly atrial flutter with 1:1 conduction. The rate of 280 is just right for atrial flutter. The waves look like atrial flutter waves, NOT like a wide ventricular complex. Recently diagnosed with intermittent paroxysmal atrial fibrillation but no EKGs available to confirm.

In the evening, a middle-aged man complained of chest pain at the nursing home. His chest pain was vague. He mentioned "cancer" and "chest". Leads II and aVF appear to have flutter waves. I diagnosed atrial flutter with 2:1 conduction. The patient converted to atrial fibrillation.

This 60-something with h/o COPD and HFrEF (EF 25%) presented with SOB and chest pain. It is not atrial fibrillation. The rhythm is indeed irregularly irregular, so atrial fibrillation must be considered. Multifocal Atrial Tachycardia 2. Here is the ECG: What do you think? Sinus with multifocal PACs 3.

She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. She presented to the emergency department after a couple of days of chest discomfort.

She reports that she is now unable to vagal out of her palpitations and is having shortness of breath and dull chest pain. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. Her initial EKG is below.

This middle-aged man with no cardiac history but with significant history of methamphetamin and alcohol use presented with chest pain and SOB, worsening over days, with orthopnea. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. The other atrial flutter types are: 1.
