Circulation: Arrhythmia and Electrophysiology, Ahead of Print. 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) 2.02];P=0.89).

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. He was awake, with a pulse of 130 and BP of 50/30.

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.

This is the prehospital ECG from an 81 year old man with acute chest pain. Here I put arrows: Arrows shows slow atrial flutter waves. Arrhythmia? Today’s case recalled that scenario for me, in that it features recognition of an arrhythmia that fooled ED staff into thinking the ECG was showing an acute infarction.

So this is an extremely slow atrial flutter with 2:1 conduction. Atrial rate 146, ventricular rate 73. I suspect that the amyloid slows the conduction of the atrial flutter. It turned out that he had a history of slow atrial flutter. There was no chest pain — and all troponins were negative.

She presented to the emergency department after a couple of days of chest discomfort. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves.

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.
