Systolic Indicator

Left ventricular systolic function is its ability to fill with blood during atrial systole, which represents half of the cardiac cycle. The most informative and accurate is the measurement of minute blood volume. Reverse, or diastolic, filling of the ventricles of the heart is also studied. The value of this indicator is important in a number of medical situations - in acute circulatory failure, atherosclerosis, myocardial infarction. For a more detailed assessment of the condition of the organ, the determination of stroke (systolic) and cardiac output is also used.

The main characteristics of filling the heart with blood have a unified calculation method and formulation, referred to as the prodromal index, indicating the potential ability of the left ventricle to fill in each cardiac cycle. Calculation of this indicator is necessary to obtain the result of a systological ECG. Preparation for the procedure includes performing a number of exercises: taking a deep breath, holding your breath, straining.

Under physiological conditions, the amount of blood entering the arteries from the left ventricle of the heart is calculated in milliliters. The conduction system triggers it into contraction and maximum volume of blood filling, then expulsion and spread throughout the body occur. This phase must be differentiated from rest, followed by diastole, which slightly increases
