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 197

Description

Baseline rhythm

Regular at 95 bpm.P-waves: visible and negative in II, III and aVF.PR interval: normal.QRS: broadened (120 ms). Axis +80º, rSR’ in V1.ST segment: depressed from V1 to V4.T-waves: negative from V1 to V4.QT interval: normal.

Zones

Two P waves are visibles with 2:1 A-V conduction.

Diagnostic

Atrial flutter with 2:1 conduction and RBBB.

Comments

The P-waves are clearly visible in II, III and aVF where they are negative, which already excludes sinus rhythm. Looking closely at the T-wave in II and III, we observe that there is a P’-wave which is not conducted. This is therefore atrial flutter wit 2:1 conduction. The morphology of the QRS is that of RBBB. The right axis deviation is secondary to a dilatation of the right-sided chambers post-transplantation.
