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 170

ECG 170


Baseline rhythm

Regular at 100 bpm.P-waves: normal but of low amplitude.PR interval: normal.QRS: micropotentials in all the leads. Normal duration.ST segment: elevated in I, aVL and from V2 to V4. Depressed in II, III, aVF and V6.T-waves: non-analysable.QT interval: normal.


ST segment elevation.


STEMI in the antero-septo-lateral region. Micropotentials.


The ST segment elevation is particularly marked because there are micropotentials of the QRS complex in all the leads. The leads in which the ST segment is elevated permit a diagnosis of antero-septo-lateral STEMI to be made.
