ELECTROCARDIOGRAPHY

ELECTROCARDIOGRAPHY

Dysfunction of the electrophysiological processes in the heart – mechanisms and manifestation. Textbook for students of the 3rd year – background for the seminars related to the electrocardiography.

The main objective of this textbook is to explain the mechanisms leading to the typical electrophysiological changes in the heart in physiological and pathological conditions and also to show the manifestation of these processes on the ECG curve.
