Pericarditis causes a reduction in cardiac output as a result of which of the following?
A) Delays in the conduction system, interfering with cardiac rhythm
B) Weak myocardial contractions due to friction rub
C) Excess fluid in the pericardial cavity, which decreases ventricular filling
D) Incompetent valves, which allow regurgitation of blood

Question

Quizplus · Accepted Answer

Excess fluid in the pericardial cavity, known as pericardial effusion, can lead to cardiac tamponade, which restricts ventricular filling and reduces cardiac output.
