In which arm is blood pressure taken?

Blood pressure, also referred to as blood pressure or blood pressure, is the pressure exerted by blood against the wall of the arteriesthe blood vessels that carry blood from the heart to the various organs and tissues of the body.

Blood pressure is measured in two components:

  1. systolic pressure: popularly known as "high pressure" or "upper". It corresponds to the blood pressure caused by ventricular systole, which is the contraction of the heart that causes blood to flow through the arteries. 120 mmHg is considered the ideal value, although it is considered normal between 110-130 in young adults and up to 150 from middle age and depending on the patient's circumstances.
  2. diastolic pressure: popularly known as the "low pressure" or "inferior". It corresponds to the arterial pressure during ventricular diastole. A value of 60 mmHg is considered ideal, and up to 90-100 mmHg can be accepted as normal, depending on age.

Blood pressure is usually taken in the arms, preferably on the left arm which is the arm that receives the pumping of the heart more directly. To take the blood pressure properly, the part of the arm being measured must be relaxed and stay at heart level.

blood pressure values on the right arm they are usually a little lower than on the left arm but only a few stitches. Nevertheless, monitoring of blood pressure in both arms is recommendedespecially in patients with cardiovascular risk. Very disparate measurements, of 10 or more points of difference between both arms, can reveal heart disease that has not yet manifested symptoms.

Some studies give figures of up to a 38% increased risk of heart attacks and other serious cardiovascular problems in patients with large differences in blood pressure readings between the left arm and the right arm.

These differences may be due to underlying problems that have not manifested themselves. For example, the difference in blood pressure between the two arms may be due to blood flow blockage by structures that are oppressing, blockage by atherosclerosis, peripheral vascular problems and other conditions of the cardiovascular system that can affect blood pressure differently in each arm.

Therefore, blood pressure should be taken preferably on the left arm and compare with readings on the right armwhich can provide useful information in the prevention of cardiovascular risk.
