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 001

Description

Basic rhythm

Regular 82 bpm.

P waves

Normal,

PR interval

Prolonged at 280 ms; depression of the PR interval in leads II, III and aVF, elevation in leads aVR and V1.

QRS

Normal axis and morphology.

ST segment

Elevation in almost all leads.

T waves

Normal.

QT interval

Normal.

Zones

ST segment elevation in almost all leads.

PR interval depression in II,III and aVF. Elevation in aVR and V1.

Diagnostic

First degree A-V block. Acute pericarditis.

Comments

The PR interval depression (in most of the leads except for aVR and V1 where the PR segment is elevated) accompanied by the diffuse ST segment elevation is a classical sign of acute pericarditis (the ST segment elevation is not always as diffuse as in the present case). The A-V block is incidental and not related to the pericarditis.
