Hemodynamic reactions in the acute phase of massive pulmonary embolism

Abstract

Massive pulmonary embolism is accompanied by the differences between a decrease in systemic and peripheral blood flow and imbalanced blood ejection from the ventricles. The results of the study suggest an association of these hemodynamic responses with redistribution of blood outfows from systemic veins whereby the relative proportion of blood outflowing to the fight atrium decreases and that of blood outflowing to the left atrium increases via systemic-pulmonary collaterals.
