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.

Basic rhythm

Non-sinus rhythm, regular at 60 bpm.

P waves

Negative in leads I and aVL.

Normal duration, axis -30 degrees, non-progression of the R wave in the precordial leads. Micropotentials in the precordial leads.

ST segment

Non-specific changes.

QT interval

Normal.


Zones

Negative P waves.
Micropotentials.

Diagnostic

Comments

It is the inversion of the P wave in I and aVL which allows us to give the diagnosis of left atrial rhythm. The micropotentials in the precordial leads are related to the shape of the patient's thorax.
