Is low heart rate healthier?

We often hear the word "arrhythmia" from doctors. The so-called heart rate refers to the number of heartbeats per minute. Generally speaking, the resting heart rate of adults will be slower than that of infants and young children, and with the increase of age, the heart rate will become slower and slower. You may have heard the saying that people with low heart rate will live longer (for example, turtles in nature have a very low heart rate, only 20 to 30 beats per minute, and their life span is really long). Is it true?/You don't say. Let's take a look. 1. What is the normal heart rate range? According to the American Heart Association, the normal resting heart rate for adults is 60 to 100 beats per minute. The average heart rate of newborns is 120- 140 beats/min, which gradually decreases with age. Until the age of 5, the heart rate will drop to 100 beats/min. Therefore, the criteria for judging bradycardia are different for different age groups. For some adults whose heart rate is 50-60 beats/min, if there is no physical discomfort, it is regarded as a normal phenomenon and there is no need to worry too much. 2. The harm of low heart rate, but it should be noted that according to cardiologists, if it is less than 50 beats per minute, it will be considered as a symptom of bradycardia, which will put your health at risk. Although not all bradycardia will do harm to health. However, for some people, especially the elderly, low heart rate needs special attention. Because this often happens at night, it is easy to cause sleep apnea. In severe cases, the patient may not wake up in his sleep. 3. Causes of bradycardia Heart tissue damage or aging: Many elderly people have bradycardia because with age, organs and tissues in the body begin to age, including the heart. Hypothyroidism: When a person's thyroid function fails, it often leads to bradycardia. Sinus node: Sinus node is the pacing point of the heart. There are many pacemaker cells here, which can cause the heart to beat, so it is very important. There is something wrong with the sinus node, which will directly affect the heartbeat and lead to abnormal heart rate. 4. Symptoms of bradycardia Although most patients with bradycardia have no obvious symptoms, some patients will have symptoms such as fatigue, dizziness, dyspnea, chest pain and palpitations. It must be noted that if you don't take strenuous exercise, but your heart beats inexplicably, you must seek medical attention in time. 5. How to improve bradycardia? Appropriate exercise: patients with mild bradycardia can exercise through appropriate exercise, such as walking, Tai Chi and other soothing exercises. Drug treatment: When bradycardia has some uncomfortable symptoms, you can take some drugs for treatment at the doctor's suggestion. Pacemaker treatment: If the bradycardia is serious and dizziness and fainting still occur after taking the medicine, then the doctor may suggest that you have an operation and use a pacemaker for treatment.
