This week we take a closer look at the AV delay by exploring the differences between the paced and sensed AV delay while focusing on the importance of the law of AV conduction.

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.

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.

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.

Dr Harry Mond shows us an example of the all too common busy ECG and explores how to report on them successfully.

Vagal Hypertonia is a topic that is often confusing and misunderstood. And although we have touched on the topic briefly in the past, Dr Harry Mond delves a little deeper in a bid to clear up any confusion.

While the QT Interval is a topic that few Cardiologists are experienced in, we review several aspects including how it can be measured, while discussing some of the surrounding controversies.

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.

This week Dr Harry Mond reviews the ventricular ectopic compensatory pause with a focus on full and partial pauses while teaching us a lesson on timing.
