Problem description:

What is the heart rate of an 80-year-old man?

Analysis:

Normal people's heart rate should be between 60- 100 beats per minute, and it is abnormal to exceed or fall below it. But the heartbeat times of different ages are different. The heartbeat of the elderly over 60 can be slowed down, but the slowest can not be less than 50 beats per minute. Because the cardiac output of athletes or strong manual workers is obviously higher than that of normal people, the heartbeat can reach about 45 times. Fever, emotional excitement, nervousness, intimidation, etc. There can be a one-time increase in the number of heartbeats, which is a reflection of the normal adjustment of the body. In short, the speed of heartbeat can reflect a person's own heart function. A strong, regular and coordinated heartbeat is one of the signs of good heart function.
