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 075

ECG 075

Description

Basic rhythm

Sinus rhythm at 75 bpm.

P waves

Normal.

PR interval

Normal.

QRS

Normal axis, duration at 110 ms (upper limit).

T waves

Non-specific changes.

QT interval

Normal.


Zones

Maximal duartion of the QRS complex.

Diagnostic

Maximal QRS maximal duration (flecainide treatment).


Comments

The P wave duration is still normal, although at the upper limit of normal values. The QRS duration at the upper limit is due to flecainide treatment which widens the QRS complex, like all class 1C antiarrhythmic drugs. T wave changes are also common during antiarrhythmic treatment.
