Tension can lead to elevated blood pressure. Tension can cause sympathetic nerve excitation, resulting in increased heart rate, increased myocardial contraction, and increased cardiac output, which leads to elevated blood pressure. For people with normal blood pressure, this elevated blood pressure is temporary and symptomatic hypertension, and with the calming of tension, blood pressure will return to normal. If a patient with hypertension is nervous, it can cause fluctuations in blood pressure, and sometimes too much nervousness can cause a significant increase in blood pressure, resulting in hypertensive emergencies or sub-emergencies. Patients with hypertension should avoid stressful situations, reduce mental stress and maintain a good state of mind, which is conducive to the control of blood pressure.
