[General and regional functions of the right ventricle in idiopathic ventricular arrhythmias].
Various aspects of the diagnosis of idiopathic ventricular arrhythmias, seen in cases where no heart changes can be detected by noninvasive investigation are discussed. Total and regional right-ventricular myocardial activity was assessed in 10 patients with moderate idiopathic right-ventricular arrhythmias. All patients underwent electrophysiologic investigation with endocardial mapping and right ventriculography. In 9 cases, biopsy from unexamined arrhythmogenic zones was taken intraoperatively for histologic studies. Arrhythmogenic foci were located in the right-ventricular outflow department in most cases of idiopathic ventricular arrhythmias. The outflow and inflow right-ventricular departments commonly demonstrated regional myocardial dysfunctions and disordered sequence of contractions of the appropriate myocardial portions during intermediate intervals of the ejection phase.
