The Atrial Fibrillation Series

September 23, 2021

In lieu of Atrial Fibrillation awareness week, we take a look at the most interesting AF in a bid to help raise awareness. Follow us to never miss a case!

1. The Artefact and Atrial Fibrillation: An Unholy Alliance

Working out whether an ECG is showing sinus rhythm with underlying artefact or atrial fibrillation is something that comes up regularly, and is the most common mistake made in ECG reporting. Dr Harry Mond explains how by digging a little deeper, differentiating between sinus rhythm and atrial fibrillation becomes simple, and why things aren’t always as they seem at first glance.

2. Unusual Ventricular Ectopy

A controversial one this week: AFib with ventricular bigeminy. Or is it? Exploring trigeminy, ventricular parasystole, pseudo-ventricular parasystole and other possibilities, this one is sure to divide opinion. Read more.

3. The Wandering Atrial Pacemaker

As a rare find Wandering Atrial Pacemaker can be mistaken for marked sinus arrhythmia with unifocal atrial ectopics. Here, we look at the tell-tale characteristics that set them apart in another interesting case study by Medical Director Dr Harry Mond. Read more.

4. Mode switching: Fast and slow pacing

Seen for the first time, the pattern in this 24hr histogram gives instantly recognisable clues about what is happening, even without looking at the tracings. Normally, we see a diurnal pattern of rate changes during the day with lower rates at night, but rarely a straight line, unless there is complete heart block (slow) or a regular continual rapid tachyarrhythmia (fast). This, however, is both fast and slow, so what is the diagnosis? We take a closer look to uncover the result. Read more.
