Atrial flutter with 2:1 conduction. The atrial flutter rate is approximately 200 bpm, with 2:1 AV conduction resulting in ventricular rate almost exactly 100 bpm. Further history revealed she had new onset atrial flutter soon after her aortic surgery, and was put on flecainide approximately 1 month ago.

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.

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?

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?

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. AFIB/AFL – atrial fibrillation or atrial flutter episodes. The left bundle and right bundle terminate in the Purkinje fibers.

The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves. The patient’s own underlying atrial rhythm is revealed at a heart rate in the mid 50s.

Atrial Tachycardia (70%) and Typical Atrial Flutter (65%) were the most common SVTs ablated. This study underscores the need for risk stratification in patients with Fontan physiology undergoing SVT ablation and informs future research directions for enhancing ablation outcomes.
