How much blood pressure and heart rate are greater than in the upright position?

When the systolic blood pressure drops more than 20mmhg, diastolic blood pressure drops more than 10mmhg, heart rate is less than 15 beats per minute, it is meaningful.

If the patient stays supine for more than 5 minutes, it will change from supine to upright. If the systolic blood pressure drops more than 20mmhg, diastolic blood pressure drops more than 10mmhg, heart rate is less than 15 beats per minute, it means that there may be orthostatic hypotension at this time.

Under normal circumstances, when the human body changes position, the body will adjust the blood pressure and heart rate to keep it in a relatively balanced range. If the value changes too much, it indicates that its ability to regulate blood pressure and heart rate has deteriorated.
