Question

Pulse deficit is the difference between:
1. Radial and ulnar pulse
2. Radial and femoral pulse
3. Radial and apical pulse
4. Radial and carotid pulse

Answer 1

Correct Answer - Option 3 : Radial and apical pulse

Concept:

• Pulse deficit refers to the difference between a radial pulse and an apical pulse rate.
• The apical pulse is assessed through the stethoscope in a sitting or lying position of the patient.
• The radial pulse is assessed by palpating the radial artery.

The pulse deficit is seen in atrial fibrillation.

Explanation:

• Due to atrial fibrillation, there is electrical-mechanical disassociation.
• This leads to poor perfusion in the periphery arteries.
• It causes pulse deficit.
