After recently discussing the two most common variations of reversed arm and leg leads, we now explore combinations of Right Arm-Right Leg Reversed, including the double twists, & all the tell-tale footprints.

Last week some of you suggested dextrocardia in response to our case of reversed arm leads. This week shows that with dextrocardia the chest leads are very different and how to avoid misdiagnosis

This week, Assoc Prof Mond discusses abnormalities commonly missed by physicians when reporting on ECGs, with a focus on reversed arm leads and how to avoid serious misdiagnosis.

Something rarely seen in Holter monitoring, the ventricular pentageminy with ventricular ectopics every 5th beat, and other curious rhythms!

Last week we proved not all bundle branch blocks are boring. Now we delve even deeper into mistaken rhythms, common misdiagnosis and those rarely talked about, including the crochetage sign

In the final part of this 2-part series, we explore even more exotic ectopy, including ventricular couplets, interpolation, unipolar bigemilets, trigemilets and more.

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.

In the final part of this 2-part series, Assoc Prof H Mond further explores the different forms of atrial ectopy including the atrial couplet, triplet, run & non-conducted types.

Assoc Prof Mond shares this case to delve into unusual and classical patterns of twisted leads in 12-lead ECG, including the double twist, and shares the tell-tale footprints of all.
