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 190

ECG 190

Description

Baseline rhythm

Regular at 60 bpm.P-waves: normal.PR interval: normal.QRS: normal with broad complexes sometimes in bigeminy.ST segment: normal.T-waves: normal.QT interval: normal.

Zones

Ventricular extrasystoles.

Diagnostic

Bigeminal ventricular extrasystoles.

Comments

This tracing is normal apart from the presence of bigeminal broad QRS complexes which correspond to ventricular extrasystoles. Indeed in the precordial leads we see there is positive concordance (the QRS complexes are positive in all the leads), which is typical for a ventricular origin of the QRS complex.
