Top 10 clinical case studies of 2020

2020 has served a plethora of different clinical cases where we’ve explored and analysed fascinating conditions from Atrial Fibrillation, Wenckeback AV block to bizarre cases of dual chamber pacing. To wrap up 2020, we’ve rounded up the top 10 cases by order of popularity.

1. Confused with complete heart block

First reported as complete heart block, a closer look reveals an irregular ventricular response. Here, we look at the 2 P-wave patterns that reveal alternating Wenckebach AV block and the characteristics of the rhythm. Read more.

2. Is this Wenckebach?

Reversed Wenckebach is a rare ECG finding, and can require a permanent pacemaker in certain cases. In this case study, we take a look at the characteristics of reversed Wenckebach, and how to recognise it on an ECG. Read more.

3. Rate dependent bundle branch block

Exploring another ventricular aberration, we look at rate dependent bundle branch block, its defining characteristics, a number of important differential diagnoses & how to avoid serious misdiagnosis. Read more.

4. Is this ventricular tachycardia?

Atrial flutter or supraventricular tachycardia with block can often give the appearance of a bidirectional tachycardia. With 8 ECG examples, we explain how to identify the characteristics of a tachycardia and reach the correct conclusion. Read more.

5. Nocturnal pauses and bundle branch block – what is this?

With nocturnal pauses and bundle branch block, what is this? With 11 traces, we delve into Wenckebach and non-conducted atrial ectopics, incl differences between termination & extension, and how atrial & ventricular ectopics terminate differently. Read more.

6. The Wandering Atrial Pacemaker

As a rare find, Wandering Atrial Pacemaker can be mistaken for marked sinus arrhythmia with unifocal atrial ectopics. We look at the characteristics that set them apart. Read more.

7. Not what it seems – Pseudo WPW

Pseudo Wolff-Parkinson-White Syndrome recently had a customer suggest we had missed the diagnosis of intermittent pre-excitation (WPW Syndrome). But Assoc Prof Harry Mond explains why it’s not what it seems. Read more.

8. Non-physiologic atrial pacing

This case looks at non-physiologic atrial pacing incl major objections to single lead rate adaptive atrial pacing and why it’s NOT AAI pacing with a ventricular minimisation pacing algorithm, plus other insights. Read more.

9. Managed ventricular pacing

A ‘bizarre’ case of dual chamber pacing with an 80ms AV delay, called us for a second opinion! With 3 different examples, we deep dive into the relationship between atrial and ventricular pacing. Read more.

10. A kaleidoscope of colour

After discussing the two most common variations of reversed arm and leg leads recently, we now explore combinations of Right Arm-Right Leg Reversed, including the double twists, & all the tell-tale footprints. Read more.
