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 079

ECG 079

Description

Basic rhythm

Sinus rhythm at 63 bpm.

P waves

Normal.

PQ interval

Prolonged at 240 ms.

QRS

Normal axis and duration.

T waves

Negative in all precordial leads and in I and aVL.

QT interval

Prolonged at 560 ms in the precordial leads.


Zones

Negatives T waves from V1 to V5.

Diagnostic

Extensive anterior subepicardial ischaemia.


Comments

We notice a significant prolongation of the QT interval in the context of extensive anterolateral ischaemia and acute coronary syndrome. Treating the ischaemia generally allows the QT interval to return to normal. Although the origin of the QT prolongation is known, other causes must nonetheless be considered, since they may exist alongside the ischaemia.
