How to read the blood pressure value:
The WHO called the systolic pressure(high pressure) above 140mmHg or diastolic pressure(low pressure) above 90mmHg as high blood pressure.
Normally, it is considered that the systolic pressure lower than 90mmHg or the diastolic pressure lower than 60mmHg, we called it low blood pressure. If low blood pressure, it may cause tissue blood hyperfusion, which might result in cytohypoxia, easy to dizziness and fatigue, severely ill people will cause the symptoms of palpitation dizziness, etc.
