you will get hold of different readings surrounded by both arms, means zilch unless the difference is extreme.
the left arm is directly coupled to the heart side and tends to read a sophisticated blood pressure reading than the right arm.just similar to when some people enjoy heart attacks,they feel it most[pain] contained by their left arm.
Distance from the heart. Only if in attendance is a marked difference, resembling 50 or 60 points would it indicate a possible blockage. Otherwise, 10 or 20 points is not unusual at all.
(And heart attack backache is most often moved out arm pain.)
Left arm is closer to the heart, ability we'll get a 'slightly' high B.P than that taken in the right arm.
