ABSTRACT
Fifty patients with idiopathic mitral valve prolapse (MVP), diagnosed by M-mode ecocardiography and free of other cardiovascular disease, were studied by kinetocardiography (KCG), to detect the presence of left ventricular dyssynergy. Kinetocardiography showed paradoxical outward movements (POM) in 27 patients these movements were pansystolic in 13 patients. The results were normal in 20 patients, unclear in 3 patients. POM were more frequently found in positions K4, K3 and K5. A comparison among results obtained with KCG and the other noninvasive techniques we used (ECG, ecocardiography and phonocardiography) showed that ectopic beats were more frequently associated with POM, which also were more frequent in patients with prolapse of both mitral leaflets and with pansistolic prolapse. Finally POM were recorded in patients with atypical or silent MVP. We conclude that KCG is an useful noninvasive technique to discover left ventricular dyssynergy in patients with MVP.
