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 162

Description

Baseline rhythm

Sinus rhythm, at 101 bpm.P waves: increased amplitude in II and aVF (3 mm). Negative amplitude increased in V1.PR interval: normal.QRS: axis + 120 degrees. R-wave predominant in V1. Micropotentials in the peripheral leads.ST segment: flat in V1, V2 and V3.T-waves: normal.QT interval: normal.

Zones

Atypical right bundle branch block, with narrow QRS complex.

Diagnostic

Extreme ECG anomalies in the context of pectus excavatum.

Comments

Atypical electrocardiographic features are observed in patients with a deformed chest wall. The changes observed entail the signs of atrial or ventricular hypertrophy, RBBB-type appearance, anomalies of repolarization manifesting themselves on the T-wave or the ST segment. Thus, several electrical signs simulating the majority of cardiac problems are produced in the course of chest deformities.
