Hypertension is one of the “three highs”. The increase in the number of people with high blood pressure year by year has given us the alarm to control our blood pressure as a major indicator of our health. As the name implies, the heart rate is the frequency of heartbeat, the heart rate is also related to the health of our body, too fast or too slow heart rate will lead to discomfort, the heart will feel uncomfortable, so what is the relationship between heart rate and blood pressure? Are they also interrelated? Is it possible that our high blood pressure and low blood pressure are related to our fast or slow heart rate? Today we will address this question. Normal adult arterial blood pressure at quiet is 90-140 mmHg systolic and 60-90 mmHg diastolic. clinical medicine has determined that a systolic blood pressure above 140 mmHg at quiet or a diastolic blood pressure consistently above 90 mmHg is considered hypertensive; a diastolic blood pressure below 60 mmHg or a systolic blood pressure below 90 mmHg is considered hypotensive. The normal human heart rate range is 60-100 beats per minute. Very often, the acceleration of the heart rate is caused by sympathetic excitation. It is often causally related to hypertension, i.e., with a fast heart rate, the risk of hypertension is higher; high blood pressure also causes damage to heart function, which leads to a faster heart rate. The faster the heart rate in hypertensive patients, the higher the risk of adverse cardiovascular events such as myocardial infarction and stroke. However, it cannot be simply said that heart rate is directly related to blood pressure. A person’s mental overstimulation and fatigue can sometimes make the heart beat faster and blood pressure higher. This means that it is your mental and physical strength that causes your blood pressure to rise and your heartbeat to speed up. There is no causal relationship between elevated blood pressure and a faster heartbeat. Instead, both blood pressure and heartbeat should be the effect, and their cause should be your nervous mental state and tired physical strength. In this way, are we able to understand the relationship between heart rate and high blood pressure!
