Heart burden is the value multiplying systolic blood pressure by pulse rate. The higher the systolic blood pressure and the faster the pulse rate, the higher the value. It is an item that literally evaluates how much burden is put on the heart, and the normal range is 7000 to 12000. If the systolic blood pressure is high and the pulse rate is fast, as in hypertensive patients, it means that the burden of high pressure continues on the cardiovascular vessels, so it is very dangerous.

Blood pressure may change due to various factors: within 1 hour after eating; after drinking alcohol, coffee, black tea (caffeinated beverage); after smoking, bathing, exercising; talking or moving during measurement; when the room temperature changes rapidly; after taking blood pressure medication; etc.
