The dangers of low heart rate

Many people think that the heart rate is not important because they only care about high blood pressure or heart problems. In fact, a too low heart rate is the main cause of these diseases, so everyone needs to be careful about arrhythmia. Some people have a too low heart rate, which can easily cause complications and may also cause difficulties in our breathing and various functions.

Heart rate Heart rate refers to the number of heart beats per minute.

A normal person's pulse is consistent with his heart rate. Although the method of measuring heart rate is simple, its clinical significance cannot be underestimated. Abnormal heart rate is a high-risk factor for many cardiovascular diseases. By measuring it, the occurrence of many cardiovascular diseases can be predicted, so that diagnosis and treatment can be carried out as early as possible to obtain better therapeutic effects.

If the patient has irregular heartbeat (such as heart rate is consistent with premature beats, etc.), the pulse rate cannot be used instead of the heart rate. It is best to measure the heart rate with a stethoscope or have it performed by a doctor.

The ideal heart rate is what the normal heart rate is. It is different when you are resting and when you are exercising.

Heart rate at rest: Generally speaking, the younger you are, the faster your heart rate. The elderly have slower heart rates than the young, and women have faster heart rates than men of the same age. These are all normal physiological phenomena. In a resting state, the normal heart rate for adults is 60 to 100 beats per minute, and the ideal heart rate should be 55 to 70 beats per minute (the heart rate of athletes is slower than that of ordinary adults, generally around 50 beats per minute).

Heart rate during exercise: A person's maximum heart rate is approximately 220 minus age. The best effect is achieved when the heart rate reaches 65% to 85% of the maximum heart rate during exercise. For example, for middle-aged people aged 40 to 50, the heart rate during exercise should be controlled at 118 to 153 beats per minute. For the elderly over 60 years old, the heart rate during exercise should be controlled at 104 to 135 beats per minute. However, for patients with heart disease, the heart rate during exercise should be controlled at 55% to 75% of the maximum heart rate.

Heart rate is inversely proportional to life expectancy

Scientists have discovered that heartbeat may be inversely proportional to life span, that is, the slower the heartbeat, the longer the life span; the faster the heartbeat, the shorter the life span. If an adult's resting heart rate is maintained at around 60 beats/minute, his or her life expectancy can reach 93 years old; on the contrary, if his or her resting heart rate is greater than 80 beats/minute, his or her life expectancy will be significantly shortened.

Heart rate changes are closely related to many diseases, especially heart disease. When an adult's heart rate exceeds 100 beats/minute (generally not more than 160 beats/minute) at rest, it is called sinus tachycardia, which is common in people who are excited, agitated, smoke, drink alcohol, drink strong tea or coffee, or in pathological conditions such as infection, fever, shock, anemia, hypoxia, hyperthyroidism, heart failure, or after the use of drugs such as atropine, epinephrine, ephedrine, etc.
