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.

Description

Baseline rhythm

Regular sinus rhythm at 83 bpm.P-waves: normal axis, presence of a second p-wave P’ completely dissociated from the first p-wave.PR interval: normal.QRS: axis -45 degrees. Duration > 120 ms. rSR’ in V1.ST segment: normal.T-waves: peaked in II and in the precordial leads.QT interval: normal.

Zones

Diagnostic

Normal ECG in a heart-transplanted patient with double atrial activity.

Comments

The double atrial activity clealy visible in III and aVF with the P- and P’-wave dissociation can only be seen in heart transplanted patients who retain atrial activity from their old atrium left in situ as well as atrial activity from the transplanted heart.
