Why Is My Blood Pressure Always Lower The Second Time I Take It (one Right After The Other)?

396545385
and.... it first came back as 134/74 - is that good or bad?

  1. Jemz - If you do it on the same arm, then it will be lower because the last time you did it caused the blood to spread in that region, so your blood pressure will be lower because the blood hasn't gone back to it normal homeostatic level.

  2. Char - Everybody's blood pressure works like that, either up or down.

    134/74 is good depending on your age. If you're young, it's not good. You should be about 120.

  3. matador 89 - RP,
    Your activity directly prior to having the reading is important, as is your state of mind. If you have not been sedentary – resting/sitting down – for about five to ten minutes beforehand and/or if you are worried or stressed, then these factors will cause an elevated reading. When your blood pressure is taken you should be sitting down and your arm from which the reading is being taken should be resting on a solid surface, horizontal and level with your heart. The fact that your second reading was lower than the first indicates that you had been in a resting position and the time that had elapsed between the first and second tests/readings relaxed your heart and it was not beating so fast and therefore the blood was not being pumped around your body as fast as before. You do not state what the second reading was. I shall explain blood pressure so that you may understand the subject more fully. Blood pressure results from two forces. One is created by the heart as it pumps blood into the arteries and through the circulatory system. The other is the force of the arteries as they resist the blood flow. The higher (systolic) number represents the pressure while the heart contracts to pump blood to the body. The lower (diastolic) number represents the pressure when the heart relaxes between beats. The systolic pressure is always stated first. For example: 118/76 (118 over 76); systolic = 118, diastolic = 76. Blood pressure BELOW 120 over 80 mmHg (millimetres of mercury) is considered optimal for adults. A systolic pressure of 120 to 139 mmHg or a diastolic pressure of 80 to 89 mmHg is considered "prehypertension" and needs to be watched carefully. A blood pressure reading of 140 over 90 or higher is considered elevated (high). High blood pressure usually has no symptoms. In fact, many people have high blood pressure for years without knowing it. That's why it's called the "silent killer." Hypertension is the medical term for high blood pressure. It doesn't refer to being tense, nervous or hyperactive. So, now you see that the reading of 134/74 takes it into the bracket of ‘prehypertension,’ as mentioned above, this may be due to exercise or stress before the first reading. However, whatever the reason was, you should be aware that a ‘one-off’ blood pressure reading that is high does not mean that you have 'high blood pressure'. Your blood pressure varies throughout the day. I shall here repeat what I have mentioned above, it may be high for a short time if you are anxious, stressed, or have just been exercising. You are considered to have 'high blood pressure' (hypertension) if you have several blood pressure readings that are high, and which are taken on different occasions, and when you are relaxed.

  4. Luke Skywalker - It isn't, and you're mistaken.

    If what you say were true, then if you kept taking readings over and over again, BP would simply get lower and lower, and lower, and that, as you'll agree, is absurd. It would be a very easy cure for so-called "hypertension", wouldn't it, -and they've been trying to cure that for centuries!

    The reality is that heart rate oscillates, up and down, every second, every minute, every hour, - the whole 24 hours. and pulse pressure (systolic minus diastolic) does the opposite.
    It rises when heart rate falls and falls when the heart rate rises. Thus, when you multiply one by the other the number you get remains roughly constant.

    That's because it reflects the cardiac output, which (at rest) is roughly constant.

    So what you think you've observed is an illusion. It's the PULSE PRESSURE that is significant, and if you observe more carefully you'll find that it is "up" when heart rate is down, and "down" when the heart rate is up.
    Because that's how the system works.
