Is this ventricular tachycardia?

Atrial flutter or supraventricular tachycardia with block can often give the appearance of a bidirectional tachycardia, which can be caused by many other things. In this latest case study, our Medical Director Assoc Prof Harry Mond explains how to identify the characteristics of a tachycardia by using a series of ECG tracings, as well as explaining how he reached the correct conclusion when asked whether an ECG was showing a ventricular tachycardia.

It’s all in the timing

Overnight Wenckebach AV block is a common finding in young people and is usually found in the presence of sinus bradycardia/sinus slowing. In this latest edition in our clinical case studies series, we look at how to identify atypical Wenckebach AV block, and how it’s affected by timing.

A bizarre ECG

Not all ECG recordings are straightforward, as illustrated by this "bizarre" ECG. In this latest edition in our clinical case studies series, our Medical Director Dr Harry Mond explains how he assessed an ECG he was asked to look at, and how eliminated incorrect solutions to the symptoms being presented.

Is this Wenckebach?

Reversed Wenckebach occurs when there is sequential shortening of the PR interval, and can require a permanent pacemaker in certain instances. In this latest case study, we take a look at examples of reversed Wenckebach, and how to recognise the rare ECG finding.

A bradycardia with pacing

All pacemaker companies have programmable algorithms to prevent ventricular pacing, but this can cause issues with Holter monitor test results. Our Medical Director, Dr Harry Mond, explains how pacemakers can confuse Holter monitor tracings, and how to correctly identify these algorithms on ECG patterns.

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 ectopic with a broad QRS

A recent Holter monitor report caused spirited debate amongst the team about whether it showed an atrial ectopic conducted with aberration, or a ventricular ectopic. CardioScan's Medical Director, Assoc Prof Harry Mond, analyses the ECG and explains who came to the correct conclusion, as well as how the confusion arose.

The Upside Down ECG

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.
