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 044

ECG 044

Description

Basic rhythm

Sinus rhythm at 103 bpm.

P waves

Normal.

PR interval

Normal.

QRS

Horizontal axis; peripheral micropotentials. Reduced voltage and non-progression of R wave in the precordial leads; rsR' pattern in V1, V2, qr pattern in V4.

ST segment

Isoelectric.

T waves

Flattened or negative in almost all leads.

QT interval

Normal.


Zones

Micropotentiels.
No R wave progression.
rSR' aspect in V1 and V2.

Diagnostic

Cardiac amyloidosis.


Comments

The combination of various abnormalities in this trace (micropotentiels, conduction disturbances and non-progression of the R wave in the precordial leads ) is suggestive of infiltrative cardiomyopathy.
