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 090

Description

Basic rhythm

Sinus rhythm at 109 bpm.

P waves

Duration 140 ms, very pronounced negative portion in V1.

PQ interval

Normal.

QRS

Axis - 20 degrees, normal duration.

ST segment

Depression in I, II, aVL, aVF and from V3 to V6. Elevation in aVR.

QT interval

Normal.

Zones

ST segment depression due to diffuse ischemia.

Diagnostic

Extensive anterior subepicardial ischaemia. Left atrial hypertrophy.

The significance of the depression (numbers of leads) elevation in aVR correspond to very extensive ischaemia, probably due to an attack in the proximal anterior interventricular artery or even the main coronary artery.
