Pericardial tamponade
The accumulation of blood in the pericardial cavity for various reasons is called hemopericardium or pericardial tamponade, which is the cause of rapid death from cardiac trauma. Due to the limited elasticity of the pericardium, acute pericardial hemorrhage of up to 150ml can limit blood return to the heart and heart beat, causing acute circulatory failure and then cardiac arrest.
