If the patient has a high pressure above 140 mmHg and a low pressure of 100 mmHg, consider the blood pressure poorly controlled. If the patient has not used any medication, sympathetic excitation is usually dominant in relatively young people, so ACEI and ARB class drugs are recommended. If the heart rate is fast, you can inhibit sympathetic excitation by doubling the Tylenol. After taking the medication, blood pressure monitoring in quiet state 2-3 times a day to monitor blood pressure and heart rate. If after two weeks, the blood pressure does not reach the target of 140/90mmHg or below, you can find the appropriate doctor to further adjust the medication and try to reach the target of 140/90mmHg or below. For patients who are already using antihypertensive drugs, but at the same time the blood pressure target is still above 145/100mmHg, consider that it may be the wrong type of drug or the dose is not enough, and use other drugs in combination to increase the antihypertensive efforts to bring the blood pressure to the target.
