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 137

ECG 137

Description

Basic rhythm

Paced at 75 bpm.

P waves

Paced.

PR interval

Normal.

QRS

Axis deviated to the right, paced with 2 spikes.

QT interval

Normal.


Zones

Atrial and ventricular spikes.

Diagnostic

Resynchronisation pacemaker working normally.


Comments

The pacemaker stimulates the atrium, right ventricle and left ventricle at the same time, which explains the presence of 2 ventricular spikes (clearly visible in lead III). This type of pacemaker is used to resynchronise the ventricles in cases of severe left ventricular dysfunction which do not respond to treatment with medication.
