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.

Isorhythmic AV dissociation with idioventricular rhythm

A recent ECG was reported as sinus rhythm with intermittent bundle branch block – but this diagnosis was incorrect. CardioScan’s Medical Director Dr Harry Mond discusses the identifying factors in the ECG, and how he reached his diagnosis of an idioventricular rhythm with isorhythmic AV dissociation.

The atrial compensatory pause

Compensatory pauses often follow atrial ectopics, but they can cause some confusion. In his latest case study, our Medical Director Dr Harry Mond clarifies the different types of compensatory pauses that can occur, as well as the typical characteristics of each compensatory pause as they present on an ECG.

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.

Complete heart block with no AV dissociation

Some cardiologists are reluctant to identify something as complete heart block when there’s no AV dissociation, but that shouldn’t be the case. Dr Harry Mond explains why you shouldn’t be afraid to call something a complete heart block when it appears that way, what clues to look for, and how to treat such a case.
