The difference between apical and peripheral pulse rates that results from decreased cardiac output when the atria fail to contract is known as:
A) pulsus paradoxus.
B) pulse deficit.
C) pulsus alternans.
D) paroxysmal pulse pressure.

Question

Quizplus · Accepted Answer

The difference between apical and peripheral pulse rates is known as pulse deficit, which occurs when there is a lack of blood flow to the peripheral vessels due to decreased cardiac output caused by the failure of the atria to contract. Pulsus paradoxus is a significant decrease in blood pressure during inspiration. Pulsus alternans is a regular rhythm with alternating stronger and weaker beats. Paroxysmal pulse pressure is not a recognized medical term.
