  • Title: [Electrocardiography in cardiomyopathies].
    Author: Gregor P.
    Journal: Vnitr Lek; 2003 Sep; 49(9):727-9. PubMed ID: 14584423.
    Abstract:
    ECG plays a predominantly screening role in cardiomyopathies. It is particularly important in hypertrophic cardiomyopathies, where atrial abnormities may be present (25%), positive voltage criteria in hypertrophy of the left ventricle (63%), pathological Q or QS wave (24%), missing septal q in V5 and V6 (49%), missing increase in the R wave in V1-V3 (29%) and high R waves in V2-V3 (15%), changes in repolarization phase of the ST-T segment (87%). The left Tawar arm blockade is particularly typical for dilatation cardiomyopathies. In arrhythmogenic cardiomyopathies of the right ventricle the epsilon ware can be found as well as negative T waves in the leads from the right precordium and ventricular arrhythmias in the shape of the left Tawar arm blockade.
