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 018

ECG 018

Description

Basic rhythm

Wide complex tachycardia at 165 bpm.

P waves

Visible in V1, dissociated from the QRS complexes.

PR interval

Random.

QRS

Enlarged, positive in V1, QS pattern from V3 to V6. Axis - 120°.

ST segment, T waves

Diffuse changes in the terminal phase.

QT interval

Not definable.


Zones

Wide QRS complexes tachycardia.
Left axis deviation.
AV dissociation nicely visible.

Diagnostic

Ventricular tachycardia.


Comments

AV dissociation is an absolute criterion for the diagnosis of ventricular tachycardia. Extreme axis deviation and the morphology of the QRS complex in the precordial leads are other criteria for this diagnosis.
