Cardiac tamponade is caused by the accumulation of fluid in the pericardial space. Because the pericardium cannot stretch if this occurs quickly, pressure rises in this space. If the pressure is higher than in the various chambers of your heart, they get compressed and some of the blood returning from your body gets backed up. This results in acute failure …
