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.

This week, Assoc Prof Harry Mond looks at the upside down ECG, and the puzzling trace that resulted. Each week, as our Director of Medicine he shares the real findings of unusual traces discovered at CardioScan, and what they reveal.

Cardiac technicians and those that report regularly on Holters may be familiar with cases like this, but the irregularities revealed in this patient are rarely reported on. Dr Harry Mond once again shares insights into another interesting trace, and what’s really going on.

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.
