This week we explore the different types of T wave changes in different leads and how to correctly diagnose non-specific T wave flattening and changes. It’s about what catches the eye!

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.

A ‘bizarre’ case of dual chamber pacing with an 80ms AV delay, called us for a second opinion! With examples of a) Atrial pacing at 50 bpm and prolonged AV delay b) Wenckebach AV block; & Ventricular paced beat after 2 secs, we deep dive into the relationship between atrial and ventricular pacing.

This week MD Assoc Prof H Mond examines the similarities between the characteristics of artefact vs non-atrioventricular Wenckebach blocks and the importance of recognising footprints for correct diagnosis.

Assoc Prof Harry Mond identifies a plethora of insights that come with studying Wenckebach sequences. This week, a definitely not boring look into atrioventricular (AV) and non-AV types, and how it’s all in the timing!

In this first of his Fun With ECG series, our MD Assoc Prof Harry Mond looks at this bizarre atrioventricular (AV) delay. Look closely at the ECG. The AV delay timings don’t make sense. The AV delay for atrial sensing/ventricular pacing (As Vp) is always longer than with ventricular sensing (Vs). In this example the AV delay is longer with As Vs. Read the full clinical case study to discover what's behind this unusual trace.

With a pause about twice the cycle length of the R to R intervals and no P, QRS or T waves, this case tackles one of the most difficult explanations in ECG interpretation and demands a revisit to the fundamentals or “footprints” of Wenckebach AV conduction to unravel what's going on.

In this rare case, we see two very unusual and critical factors that together lead to atrial oversensing and “apparent” violation of the lower rate limit; a very narrow zone of open atrial sensing and far-field R wave sensing. While the first time MD Assoc Prof Harry Mond has seen this as atrial pacing, he explains how the issue can be very easily solved, reminding us, that normally there's no R wave sensing with AAI(R) pacing.
