title: [The significance of ventricular arrhythmias during muscular work: correlations with coronary heart disease (author's transl)].
abstract: The incidence of ventricular arrhythmias during muscular work in 400 patients hospitalized for clear or suspected coronary artery disease who underwent coronaroangiography and exercise test was studied. The correlations between the arrhythmias and some hemodynamic parameters and the coronaroangiogrphy patterns and left ventricle cineangiography were investigated. None of the factors that were supposed to be significant in the mechanism of the ventricular arrhythmias, such as high left ventricular end dyastolic pressure, modified myocardial contractility, previous myocardial infarct, or higher lesions of coronary arteries, gave significant correlations. In the present study, the ventricular arrhythmias during muscular work do not seem to be of diagnostic significance.
