Physiologically Speaking

JULY 26, 2024

Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. This irregular sleep pattern misaligns circadian rhythms and disrupts physiology. ICYMI: On Wednesday, I published my video interview with Dr. Andrew Koutnik. “The shorter your sleep, the shorter your life.”

There is the appearance of STE in inferior leads II, III, and aVF (with STD in aVR), but this is entirely due to flutter waves which are only seen in those leads. Also, the atrial flutter in this case is relatively slow like in many other cases we've shown. Atrial Flutter with Inferior STEMI? Is this inferor STEMI?

Demographic, clinical, and outcome variables over 5 years were compared between patients with and without SVT recurrence.Results:Mean age of 25 patients (56% male) at time of SVT ablation was 31.5 ± 7.2 Atrial Tachycardia (70%) and Typical Atrial Flutter (65%) were the most common SVTs ablated.

By understanding the nuances of abnormalities detected in Cardiomatics and interpreting detailed reports, healthcare professionals can intervene promptly to prevent adverse outcomes. AFIB/AFL – atrial fibrillation or atrial flutter episodes. The left bundle and right bundle terminate in the Purkinje fibers.

The rhythm differential for narrow, regular, and tachycardic is sinus rhythm, SVT (encompassing AVNRT, AVRT, atrial tach, etc), and atrial flutter (another supraventricular rhythm which is usually considered separately from SVTs). Therefore this patient is either in some form of SVT or atrial flutter. If so, why?
