An Accumulation of Excess Fluid in the Pericardial Space

Question

An accumulation of excess fluid in the pericardial space
A) causes external compression of the heart.
B) depresses the SA node, thereby eliminating pacemaker activity.
C) causes valvular stenosis.
D) causes a left-to-right shunt.

Accepted Answer

An accumulation of excess fluid in the pericardial space causes external compression of the heart, which can lead to cardiac tamponade and compromise cardiac output. This can be a life-threatening condition if not promptly and appropriately managed. Choices B, C, and D are not accurate descriptions of the effects of pericardial effusion.
