However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem

.A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
