See our other blog posts of hypothermia and Osborn waves -- Massive Osborn Waves of Severe Hypothermia (23.6 Altered Mental Status, Bradycardia == MY Comment , by K EN G RAUER, MD ( 2/2 /2024 ): == Dr. Meyers began today’s case with the clinical challenge of asking you to identify the underlying cause of ECG #2. Is there a long QT?

Resuscitation was initiated and this ECG was obtained: Likely AFib (irregularly irregular) with bradycardia. In addition to marked bradycardia — could there be high-grade AV block? STD in V2 from posterior MI can "pull down" the STE in V1 and negate it. Figure-2: ECG #2 — recorded on arrival in the ED ( See text ).

. = My Comment by K EN G RAUER, MD ( 3/15 /2023 ): = I found today’s case highly instructive in highlighting a number of important aspects regarding the presentation and initial treatment of a patient who presents to the ED with new AFib. I focus my comment on a few additional aspects regarding new AFib.

I've copied KEY points from My Comment in the August 6, 2022 post in Dr. Smith's ECG Blog — regarding the answer to this question. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). RBBB in blunt chest trauma seems to be indicative of several RV injury.

I have periodically called attention to examples of the Ashman phenomenon as they occur in Dr. Smith's ECG Blog ( See My Comments in the January 5, 2020 post — the June 17, 2020 post — and the March 30, 2023 post , among others ).

Additionally, her beta-blocker dose had been decreased because of bradycardia, further predisposing her to atrial flutter. For example: Statistical likelihood that the regular WCT in ECG #1 might be AFlutter ( instead of VT ) is greatly increased in a patient with AFib who is taking Flecainide.
