This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? Troponins 34>33>43, likely secondary to myocardial injury from tachycardia. Is longterm endurance-training a risk factor for AFib and AFlutter? == Why is Today's Initial Rhythm AFlutter? Sinus tachycardia does not go this fast.

But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). Similar-looking wide beats #7,13,14 must also be aberrantly conducted supraventricular impulses — and since P waves are lost after beat #6 and subsequent R-R intervals are irregular — beats #7-thru-16 constitute a run of rapid AFib.

Initial vital signs include: NIBP 99/58 HR 150-160 (trend) RR 10 (spontaneous, but shallow) SpO2 86 (RA) BBS CTA The initial rhythm strip is attached: Figure 1 There is a wide complex tachycardia of varying morphology, amplitude, and R-R cycle length. The rS configuration in Lead I displays a persistent rightward axis.

Answer : you must treat the patient's underlying condition causing sinus tachycardia, and repeat the ECG at the lower heart rate. They measured QTc while patients were in Afib and then again after conversion, when they were in sinus rhythm. Heart 2002;87:220228 This 2017 article by Vandenberk B et al. which is 0.6
