Answer :
Answer: The difference between the apical pulse and the radial pulse is called the pulse deficit.
Explanation:
Radial pulse is the pulse taken at the periphery i.e at the wirst. And the apical pulse is the pulse over the top of the heart primarily at the apex beat. Pulse deficit may be defined as the difference between the pulsations at the periphery and the heart beats. Pulse deficit may be present in the case of atrial fibrillation or premature ventricular beats.
