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 158

Description

Baseline rhythm

Regular at 39 bpm.P-waves: non visible.PR interval: non measurable.QRS: broadened (140 ms), micropotentials in the peripheral leads.ST segment: depression in II, III and from V2 to V6..T waves: negative from V2 to V6.QT interval: prolonged.

Zones

Diagnostic

Idioventricular rhythm without p-waves in the context of hyperklaemia.

Comments

This ECG is typical of hyperkalemia with absence of p-waves and very broadened QRS complexes. The T-waves are often peaked during hyperkalemia, which is also a sign of hyperkalemia. We see a fusion between the QRS complexes and the T.wave, which in the next stage provokes an agonal rhythm represented by oscillation of the base line.
