A. Pulsus Dicroticus.

B. Pulsus bisferiens.

C. Catacrotic pulse.

D. Hypokinetic pulse.

Correct Answer » A Explanation

Ans:A. Pulsus Dicroticus.

Dicrotic pulse

• It is a type of pulse characterized by a percussion wave in systole and a prominent dicrotic wave in diastole.

• Physiologically, the dicrotic wave is the result of reflected waves from the lower extremities and aorta.

• Conditions associated with low cardiac output and high systemic vascular resistance can produce a dicrotic pulse.

• Conditions associated with low systemic vascular resistance and a compliant aorta (e.g. sepsis) can also produce a dicrotic pulse.

• In contrast to an anacrotic or bisferiens pulse, the 2 peaks in a dicrotic pulse occur in systole and diastole (as opposed to both occurring in systole).
