[Apex carotis diagram and benign systolic murmurs].

The apex-carotis diagram is a new mechanocardiographic, non invasive method consisting of integration of the carotidogram and apexcardiogram--synchronously recorded. The value of the amplitude height of these curves at every 0.025 sec are transferred to an orthogonal coordinate system and later the points connected in a chronological order thus obtaining the apex-carotidogram (ACD). ACD have been constructed in 62 healthy subjects and in 26 people with innocent systolic murmur, aged between 14--65 years. Our investigation showed no difference between the control group and the people with innocent murmur. The points of connection, lines, segments, fields and axis of ACD were the same in both groups. The angles alpha, beta, gamma, delta, epsilon measured quantity and calculated showed no statistical difference (p greater than 0.05).
