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 184


Baseline rhythm

Regular at 75 bpm.P-waves: normal.PR interval: normal.QRS : Q-waves in II, III and aVF and from V2 to V4.ST segment: elevated in II, III and aVF.T-waves: negative in I and aVL.QT interval: normal.


ST segment elevation.
Q waves.


Sequelae of an anterior infarct and inferior STEMI.


Straightaway, we see ST elevation in the inferior leads. This corresponds to a STEMI in this territory. The presence of Q-waves in the same leads indicates that necrosis has already in part set in. The Q-waves from V2 to V4 are the consequences of an old anterior infarct.
