Szívburokfolyadék refers to the fluid that is normally present in the pericardial space, the thin sac that surrounds the heart. This fluid acts as a lubricant, allowing the heart to beat smoothly within the chest cavity without friction. Typically, the amount of pericardial fluid is very small, usually between 15 and 50 milliliters. Its primary function is to reduce friction between the two layers of the pericardium, the visceral layer that covers the heart and the parietal layer that lines the outer sac.
An increase in the amount of pericardial fluid is known as pericardial effusion. This condition can arise
