This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? 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.

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) Postablation chest pain consistent with pericarditis was reduced with colchicine (4% versus 15%; HR, 0.26 [95% CI, 0.09–0.77];P=0.02) mg twice daily or placebo for 10 days. 2.02];P=0.89).

This is the prehospital ECG from an 81 year old man with acute chest pain. There are 2 atrial "bumps" for every QRS. Here I put arrows: Arrows shows slow atrial flutter waves. My "Go To" Leads when I find myself searching for atrial activity are leads II, III, aVF — lead aVR — and lead V1. Look at V1.

A male in his 60's called 911 for dizziness and chest pain, onset with exertion. Here is his initial rhythm strip (it is not a full 10 seconds): Wide complex tachycardia, rate 235 This is a very wide complex regular tachycardia at a rate of 235. It should be considered to be Ventricular Tachycardia and treated as such.

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. Here was his ED ECG: There is sinus tachycardia (rate about 114) with nonspecific ST-T abnormalities. BP:143/99, Pulse 109, Temp 37.2 °C

She reports that she is now unable to vagal out of her palpitations and is having shortness of breath and dull chest pain. We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. There are no P waves preceding the QRS complexes, and no clear flutter waves.

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". He mentioned "cancer" and "chest". There is a narrow complex tachycardia at a rate of 130. Leads II and aVF appear to have flutter waves. Is is sinus?
