ECG Directory

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 031

ECG 031

Description

Basic rhythm

Sinus rhythm, regular at 70 bpm.

P waves

Normal.

PR interval

Normal.

QRS

Normal.

ST segment

Oblique elevation and descending in V1 and V2.

T waves

Inverted in V1, V2.

QT interval

Normal.

Zones

Atypical Rigth Bundle Branch Block in V1 and V2. St segment elevation in V1 and V2.

Diagnostic

Brugada syndrome (ECG type I).

Comments

The morphology of the QRS complex in V1 is characteristic of a complete right bundle branch block. However, the ST segment elevation is highly suggestive of Brugada syndrome due to its significance and its oblique and descending nature. An injection of flecainide or ajmaline could perhaps uncover it. This trace shows type I Brugada syndrome. In type II and III the ST segment morphology is different. A history of syncope is an absolute indication for the implantation of an internal defibrillator.
