The author discusses possibilities and the importance of electrocardiography in different types of cardiomyopathies. ECG plays a fundamental role in particular in hypertrophic cardiomyopathies where it serves for screening. This pertains to fully developed forms as well as to latent morphologically not yet expressed forms and also to some special types of the disease (apical forms). ECG can be a very important method also in right ventricular arrhythmogenic cardiomyopathies (again above all for screening in paroxysmal ventricular tachycardias in left bundle branch block). In other types of cardiomyopathies the importance of ECG is small.
