The reason that blood pressure diastolic pressure is low?

summary

Diastolic pressure is when people's heart diastolic, arterial elastic contraction, the pressure is called diastolic pressure, also known as low pressure. When the heart is diastolic, the aortic pressure decreases. The lowest arterial pressure in the end diastolic period is called diastolic pressure. The normal diastolic pressure of adults is < 90mmHg (12kpa), and the unit of blood pressure is kPa, 1kPa = 7.6mmhg. That's what people often say, 60 to 90. The reason that blood pressure diastolic pressure is low? Let's talk about it

The reason that blood pressure diastolic pressure is low?

The change of heart rate has great influence on hypotension. Heart rate increases, diastolic period is short, in a short period of time through the small artery flow to the peripheral blood is less, so the end of the diastolic period in the aorta blood flow increased, resulting in high pressure.

Blood pressure measurement is affected by many factors, such as emotional excitement, tension, exercise, etc; If the blood pressure reaches or exceeds 140 mmHg systolic blood pressure and (or) 90 mmHg diastolic blood pressure at least three times in a quiet and sober condition, it can be considered as hypertension. When the blood pressure is lower than 90 / 60 mmHg, it is called hypotension.

The current blood pressure, especially the low diastolic blood pressure, is estimated to be related to oral antihypertensive drugs. Of course, the large pulse pressure difference is also related to many factors, such as heart valve insufficiency. In view of the situation of the old man, it is not recommended to continue taking antihypertensive drugs, or reduce the amount under the guidance of doctors, because the diastolic blood pressure is too low, which is easy to lead to insufficient cardiac artery perfusion, but prone to problems.

matters needing attention

To talk about diet, eat less or no greasy, spicy, pickled, marinated and pickled food. High salt diet will increase blood pressure, so the amount of salt should not exceed 6 grams per day. When cooking, use measuring tools to measure the amount of salt added, such as special salt spoon, or substitute products such as salt and vinegar.
