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 211

Description

Baseline rhythm

Regular at 43 bpm.P-waves: non-visible.PR interval: non-measurable.QRS : broadened (120 ms). Axis -45º.ST segment: normal.T-waves: peaked in I, II and from V2 to V6.QT interval: prolonged (480 ms).

Zones

Diagnostic

Hyperkalemia. Idioventricular rhythm.

Comments

This ECG is typical of hyperkalemia with absence of P-waves and very broadened QRS complexes. The T-waves are very peaked which is equally characteristic of hyperkalemia. We note the beginnings of fusion between the QRS and the T-waves which in the next stage initiates an agonal rhythm represented by an oscillation of the baseline.
