AFIB Arrhythmia Bradycardia 
Cardiomatics
APRIL 5, 2024
Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes. Other times, an irregular recording can signal a medical emergency, such as a myocardial infarction or a dangerous arrhythmia. Usually does not exceed 160 bpm.

Background The rising adoption of wearable technology increases the potential to identify arrhythmias. Those with arrhythmias or non-diagnostic EKGs were sent 7-day monitors. The EHR was reviewed after 3 years to determine if participants developed arrhythmias. Mean age was 50.5 (SD years, and 46 (53.3%) were female.

. = 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.

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. -- Read this ECG -- Osborn Waves and Hypothermia (this is the "Figure" above) What does LBBB look like in severe hypothermia?

Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). NOTE: Prediction of cardiac contusion "severity" on the basis of cardiac arrhythmias and ECG findings — is an imperfect science. RBBB in blunt chest trauma seems to be indicative of several RV injury.

Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. 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.

Additionally, her beta-blocker dose had been decreased because of bradycardia, further predisposing her to atrial flutter. During hospital admission she had a variety of atrial arrhythmias, which eventually resolved, likely due to her decreasing flecainide level. Note QRS widening for beats #14-thru-18 in ECG #3.
