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 191

Description

Baseline rhythm

Sinus rhythm at times.P-waves: normal when they are visible.PR interval: normal when they can be measured.QRS: normal when it is narrow.ST segment: variable following the QRS complex.T-waves: variable.QT interval: prolonged.

Zones

Diagnostic

Torsades de pointes following acquired long QT.

Comments

The first QRS complexes are normal but with a prolongation of the QT interval and bradycardia. Then follows a complex called “intermediate complex” which initiates a ventricular arrhythmia typical of torsades de pointes. There is severe bradycardia with at times emergence of a nodal rhythm.
