Physiologically Speaking

Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. This irregular sleep pattern misaligns circadian rhythms and disrupts physiology. Deep sleep: Each percent increase in deep sleep was associated with a lower risk of atrial fibrillation, depression, and anxiety.

Then, the current flows to an area known as the bundle of His, which divides into two branches (LBB and RBB) and is the only physiological pathway connecting the atria with the ventricles. Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes.

The other leads that most often manifest readily identifiable 2:1 atrial activity — are leads aVR , V1 and/or V2 — so I favor first checking out these 6 leads whenever looking for AFlutter. ECG #3 was obtained during treatment of this patient's AFlutter — at approximately the same time that ECG #1 was obtained.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
