Abstract
DE MICHELI, Alfredo; ARANDA, Alberto; ITURRALDE, Pedro and MEDRANO, Gustavo A. On the ventricular arrhythmias in chagasic chronic cardiomyopathy. Arch. Cardiol. Méx. [online]. 2006, vol.76, n.3, pp.320-323. ISSN 1665-1731.
Some authors have shown a high prevalence of electric circuits localized in the epicardium in Chagasic cardiomyopathy Other authors have found in these patients, during electric mapping, mid-diastolic potentials and earlier myocardial activation in epicardial regions than in the endocardium. In a previous study, we found electrocardiographic signs of subepicardial ischemia in 66% of seropositive Chagasic patients against 16% of seronegative Chagasic ones. In the case presented here, a Chagasic dilated cardiomyopathy, we found electrocardiographic signs of subepicardial injury in the left free ventricular wall, related with histological findings of lymphocytic inflammation in these regions. In contrast, the endocardium was completely free from inflammation foci.
