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 169

ECG 169

Description

Baseline rhythm

Regular at 92 bpm.P-waves: increased amplitude in II, III and aVF with an amplitude > 2 mm.PQ interval: normal.QRS: right axis deviation with an axis of + 110º. r/s < 1 in V6. Tall R’-wave in V1.ST segment: isoelectric.T-waves: normal.QT interval: normal.


Zones

S>R typical for right axis deviation.
r/s ratio < 1.
Tall R wave favoring of right ventricular hypertrophy.

Diagnostic

Atrial and right ventricular hypertrophy.


Comments

The right axis deviation coupled with an r/s relationship <1 in V6 and the tall R’-wave in V1 are typical of right ventricular hypertrophy. The tall P-wave in II and III indicates right atrial dilatation.
