Résumé
A prospective study was organized to clarify the clinical association of localized intraventricular conductions [LIVCD]. Fifty patients with symptoms suggesting cardiac origin were studied and subjected to chest X-ray, E.C.G, holter ambulatory monitoring, and treadmill test. The results showed that LIVCD seems to be acquired. Ischemic heart disease constituted the most frequent associated condition [42%]. Hypertension not associated with ischemia constituted the next frequent condition [30%]. Obesity and diabetes mellitus account for [10% and 8%], respectively. No definite association could be found in the remaining 10% of cases, a finding which might be related to other factors e.g. sclerodegenerative affection, myocaraditis, cardiomyopathy. Indeed patients with LIVCD are in need for long-term follow up to monitor the progression of this condition to other types of intraventricular conduction defects
