Is a heart rate of 69 normal?

Generally speaking, there are many reasons for abnormal heart rate. However, if abnormal heart rate occurs frequently, you must pay attention to it. Abnormal heart rate can cause many diseases in the body, but a normal heart rate does not necessarily mean that it will not cause heart disease. If you do not pay attention to maintenance, it is easy to cause heart abnormalities. If you want to be healthy, you need to protect your heart well.

Is a heart rate of 69 normal?

The normal range of heart rate at rest is 60-100 beats/minute. 69 beats/minute is within the normal range, so don't worry. If the heart rate is lower than 60 beats/minute, it is considered bradycardia, which can be seen in athletes, manual laborers, patients with heart disease, and hypothyroidism. If the heart rate is 100 beats/minute, it is tachycardia, which can be seen in various heart diseases, hyperthyroidism, fever, strenuous exercise, emotional excitement and tension, drinking alcohol, coffee and other stimulating beverages, etc. A normal heart rate does not mean that there is no heart disease.

The ideal heart rate for a normal adult should be 55 to 70 beats per minute, but heart disease may cause the heart rate to speed up or slow down. According to the changes in heart rate, it is clinically divided into tachycardia and bradycardia. Next, I will give you a brief description:

Tachycardia is a heart rate that exceeds 100 beats per minute. There are many clinical causes of tachycardia, which can be divided into physiological and pathological causes depending on whether the disease is present. When you are excited, your blood vessels dilate and your heart beats faster to maintain blood pressure. The heart rate can also be increased due to factors such as smoking, drinking, and drinking strong tea or coffee. In addition, some patients need to take drugs such as adrenaline due to their illness. Adrenaline is an agonist of the β1 receptors of the conduction system and the sinoatrial node. When taking adrenaline, it will strengthen the contraction of the myocardium, accelerate the conduction of excitement, the heart rate will increase accordingly, and the excitability of the myocardium will also be significantly improved.

Bradycardia means that the heart rate is significantly lower than 60 beats/minute. The causes of bradycardia can also be divided into physiological and pathological. Athletes and people who engage in physical labor for a long time generally have a lower heart rate than normal people. Due to low thyroid function, patients with hypothyroidism have decreased secretion of thyroid hormones, the body is in an inhibited state, and the heart rate decreases accordingly. When the body takes an overdose of drugs such as propranolol, it may also cause a decrease in heart rate. Propranolol is a beta-receptor blocker in the body, which has a blocking effect on both beta-1 and beta-2 receptors in the body. Its mechanism is exactly the opposite of the principle of adrenaline stimulation. Other drugs that can cause a slow heart rate include digitalis and quinidine.

Clinical studies have found that a heart rate that is too fast or too slow can be harmful to the body. So how can we maintain a heart rate of 60 to 100 beats per minute in life? First of all, we should exercise our bodies regularly. Long-term participation in moderate physical exercise will slow down our resting heart rate. Secondly, a healthy lifestyle is also necessary. Staying up late and drinking strong tea before bed can cause the resting heart rate to increase. We should try to avoid these bad habits. When the abnormal heart rate is caused by an illness, we should go to a local regular hospital for treatment as soon as possible to reduce the damage to the heart, avoid myocardial ischemia and other conditions, and prolong our life.
