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 215

Description

Baseline rhythm

Regular at 170 and 90 bpm.P-waves: normals when visible.PR interval: normal.QRS: broadened (120 ms) in tachycardia, otherwise normal.ST segment: normal in sinus rhythm.T-waves: normals.QT interval: normal.

Zones

Normal PQ interval, QRS complex et QT interval.

Wide QRS tachycardia with inferior axis.

Diagnostic

Ventricular tachycardia arising from the right ventricular outflow tract.

Comments

This trace is a wide QRS complex tachycardia. The morphology of the QRS complex is typical for a ventricular origin, especially in aVR (Q wave > 40 ms) and in the precordial leads. The vertical axis is typical for a tachycardia arising form the right ventricular outflow tract.
