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 187

ECG 187

Description

Baseline rhythm

Regular at 60 bpm.P-waves: bifid.PR interval: normal.QRS : normal duration. rSR’ in V1. Axis + 110º.STsegment: normal.T-waves: negative from V4 to V6.QT interval: normal.


Zones

Bifid P waves.
Atypical and incomplete right bundle branch block.

Diagnostic

Bifid P waves. Incomplete right bundle branch block. Non-specific changes in the terminal phase.


Comments

This tracing is that of a female patient with pectus excavatum. With this pathology one often sees incomplete right bundle branch block and abnormal P-waves sometimes with an increased amplitude in II, III and aVF. This is not the case here. The changes in the terminal phase are non-specific. Whenever incomplete right bundle branch block is present with a right axis of the QRS complex and bizarre P-waves, a diagnosis of pectus excavatum should be considered.
