<prompt> Most impoant factor determining the strength of a pulse?Mean BPTPRPulse pressureNone  <response>: Ans. is c i.e., Pulse pressureThe Strength or amplitude or volume of pulse depends on the volume of blood ejected out with each beat Stroke volumeand extent of elasticity compliance of aerial wall, both of which are determinant of pulse pressure i.e. systolic Pressure - diastolic pressure.The pulse strength indicates the strength of ventricular contraction and cardiac output, If The pulse is strong, then systolic pressure is hiCh. If it is weak systolic pressure has fallen and medical intervention may be warranted.
