Welcome to this interactive ECG course.

Although it is one of the oldest paraclinic exams, dating back to the late 19th century, the ECG is still of crucial clinical use. This examination often still poses problems of interpretation to the medical practitioner.

This course aims to help the student, the practicing physician and even the trained cardiologist to improve his knowledge in electrocardiography. It consists of 250 traces of varying complexity with a description of each one by experts. This allows the reader to compare his analysis with that of the experts. In addition, the areas of interest of the ECG can be activated to be clearly highlighted.

We hope that these plots will be useful to readers and will improve their knowledge.

The ECGs are available sorted by keywords and categories.

ECG 034

Description

Basic rhythm

Regular tachycardia at 150 bpm.

P waves

Dissociated from the QRS complexes.

PR interval

Cannot be evaluated.

QRS

RS pattern in V1 horizontal axis. Duration 130 ms. In V1 and V2: R wave > 60 ms and notching of the descending part of the S wave; in V2-V3: from R wave to the nadir of the wave.

QT interval

Normal.

Zones

Diagnostic

Post myocardial infarction ventricular tachycardia.

Comments

The extrasystole from the previous ECG has the same morphology as the QRS complexes of ventricular tachycardia. Palpitations and/or wide QRS complex tachycardia following myocardial infarction have to be considered as synonymous with ventricular tachycardia until the opposite is proven.
