【 摘 要 】

To detect complex ventricular arrhythmias in different stages of chronic chagasic cardiopathy, the results of exercise testing to 24 hours Holter monitoring have been compared. We evaluated a group of 71 patients, half women, aged 51±10.3, with no others associated diseases. These patients were separated in 4 groups according to degree of cardiac involvement. Statistical data can be found elsewhere in the study. In group IA, Holter monitoring detected 4.3% of complex ventricular arrhythmias, group IB 25%, group II 55% and group III 90%. We found no difference between Holter and exercise testing in the detection of complex ventricular arrhythmias in groups II and III (p = ns). In groups IA and IB we found 100% concordance, concerning the no detection of complex ventricular arrhythmias by exercise testing seen by two independent examiners. In group II there was a 70% concordance (kappa=0.368, p=0.003) and 90% in group III (kappa=0.78, p=0.002). Different results were found, concerning the presence of complex ventricular arrhythmias, among patients in the initial and advanced stages of chronic chagasic cardiopathy. In groups II and III we found no difference between the two methods in the detection of complex ventricular arrhythmias. It seems reasonable to recommend either Holter on exercise testing in groups IA and IB if progression of disease is noticed.
