What is the normal heart rate during sleep?

The normal heart rate during sleep is 60-100 beats per minute.

Heart rate refers to the number of beats of the heart per minute and is usually regulated by the autonomic nervous system of the heart. The heart rate of a normal adult in a quiet and relaxed state is usually between 60 and 100 beats per minute. Specific indicators can be affected by factors such as age, mental state, and activity level.

Heart rate can be obtained by measuring the pulse or using a heart rate monitoring instrument, which can help assess cardiovascular function. If the heart rate is found to be persistently low or high, blood tests, imaging examinations and other examinations should be performed promptly to confirm the diagnosis.
