Literature shows that pulse rate has a relationship with blood pressure, and pulse rate changes are more closely related to diastolic blood pressure fluctuations.
Pulse rate, except for atrial fibrillation, generally represents the heart rate. When the sympathetic meridian is excited, the heart rate increases, the myocardial contractility increases, the pulse rate increases, and the blood pressure rises.
However, some patients with tachycardia, the heart rate is faster, so that the ventricular diastolic period is shortened, the ventricular filling volume and the ejection volume is insufficient, so that the blood pressure drops, then the pulse rate increases and the blood pressure decreases; when the blood pressure is lowered, it can stimulate sympathetic excitation, and the heart rate increases, then the pulse rate increases as well, and the blood pressure decreases at this time, and the heart rate increases.
Although the pulse rate may be related to the blood pressure, the specific mechanism has not been clarified.
Warm reminder: If you find that the pulse rate or blood pressure is abnormal, it is necessary to seek medical treatment in time, accompanied by any physical discomfort symptoms, it is necessary to provide timely feedback to the doctor.
