Radiofemoral delay is an important clinical sign that help
to detect the coarctation of aorta
How to elicit radiofemoral delay?
To detect the radiofemoral delay you have to palpate the
radial and femoral artery simultaneously.Normally the time taken for the pulse
wave to reach the radial artery after the cardiac systole is 80 milliseconds
and for the femoral artery it is 75milleseconds.If the femoral pulse is delayed
compared to radial pulse it is called as radiofemoral delay.
Causes of radiofemoral delay
Coarctation ol aorta
Atherosclerosis of aorta.
Thrombosis or embolism of aorta
Aortoarteritis.
