Question

Cardiac tamponade is a disease process in which blood fills the sac around the heart called the pericardium, thereby increasing the pressure immediately outside the heart. How will this affect the volume of the ventricles (heart chambers) and systemic blood pressure?

Cardiac tamponade is a disease process in which blood fills the sac around the heart called the pericardium, thereby increasing the pressure immediately outside the heart. How will this affect the volume of the ventricles (heart chambers) and systemic blood pressure? O The ventricles will increase in volume and blood pressure will increase The ventricles will decrease in volume and blood pressure will increase The ventricles will increase in volume and blood pressure will decrease. The ventricles will decrease in volume and blood pressure will decrease. O O

Explanation / Answer

Cardiac tamponade is a condition characterised by collection of fluid in the pericardial space along with cardiac dysfunction. Cardiac tamponade results in a condition called as Beck's triad which includes decreased blood pressure, elevated jugular venous pulse and muffled heart sounds. Therefore in cardiac tamponade, the ventricles will decrease in volume and blood pressure will decrease (option 4).
