[Normal echogram of the mitral valve. Study of 50 normal, military-age subjects].

The mitral echograms of 50 normal subjects of military age were studied and basic parameters compared with anthropometric data and heart frequency; unlike what has been found by other workers, no significant statistical correlation was observed. Mean values of the parameters used are not substantially different to those reported in the literature consulted although deeper statistical studies are required if more valid standards are to be found.
