AbstractCalculating of cavities of ventricles of the heart according to echocardiography, having big values in cardiology is considered in the article. Here the main attention is concentrated on the left ventricle of heart, as having the most correct form and the best available visualization. In article the area and length of cavities are defined, installing the ultrasonic sensor in a parasternal position on a short axis, at the level of the end of shutters of the mitral valve. Further, the ultrasonic sensor is installed in the apical four-chambered with access. The image is fixed, studied the long axis of the cavity is divided evenly pieces. Each of its points of division, held parallel to a line perpendicular to inter ventricular septum. Each short-axis corresponds to certain areas of the cavities of the ventricles, which are also perpendicular to inter ventricular septum. Corresponding to each piece of the volume of the cavities of the ventricles of the heart is determined by calculating the approximate volume of a truncated cone. Then summing all of the volumes, we finally obtain the formula to calculate the volume of the cavities of the ventricles of the heart. It is shown that this method is accurate and reliable over the other method.
