title: [Studies of the phasic structure of the cardiac cycle by means of echocardiography].
abstract: A synchronous analysis of the variations in the diameter of the left ventricle, the mural movements of the left atrium and the mitral and aortal cusps allows the division of the cardiac cycle into 13 phases and intervals. The duration of phases calculated with the help of echocardiography is in agreement with the data provided by other methods.
