What does systolic and diastolic mean?

Systolic blood pressure refers to the side pressure produced by arterial blood on the blood vessel wall during systolic period. Diastolic blood pressure refers to the side pressure produced by arterial blood on the blood vessel wall during diastolic period.

Under normal circumstances, the systolic blood pressure of the human body in a quiet state is 90-139 mmHg, and diastolic blood pressure is 60-89 mmHg. If the systolic blood pressure is higher than 140 mmHg, and/or the diastolic blood pressure is higher than 90 mmHg, it indicates that the body has high blood pressure.

If the systolic blood pressure and diastolic blood pressure are abnormal, it is recommended to go to the cardiovascular department of the hospital for examination.
