Heart rate 8090. Is that normal?

Heart rate 80-90 beats/min is generally normal.

Heart rate is the number of beats per minute of the heart, which is one of the basic vital signs of the human body. It can be used to monitor physical condition and diagnose arrhythmia, cardiomyopathy, heart failure and other diseases. Because heart rate is easily affected by environment, exercise, diet, etc., it is usually recommended to measure it in a quiet state. Healthy adults generally measure heart rate 60-100 beats/min in a quiet state, and 80-90 beats/min is between the above ranges, usually indicating symptoms. If the heart rate exceeds 100 beats/min, it indicates that the index is high, which may be related to factors such as strenuous exercise, emotional agitation, hyperthyroidism, etc.; if the heart rate is lower than 60 beats/min, it indicates that the index is low, which may be related to factors such as long-term exercise, hypothyroidism, heart failure, etc.
