35-year-old female heart rate over 90 for a long time

Heart rate refers to the frequency of a person's heartbeats per minute, and is also a factor that indicates whether the human body is healthy. The normal heart rate is between 60 and 100 beats per minute. If it is lower than this frequency, it means that the patient has bradycardia. If it is higher than this frequency, it is a sign of tachycardia. Both of these symptoms require certain treatment. The following is a detailed introduction to the relevant knowledge about heart rate.

Heart Rate: A professional term used to describe the cardiac cycle, which refers to the number of heart beats per minute, based on the first sound.

Heart rate. In modern Chinese, heart rate is interpreted as "the frequency of heart beating". Frequency is the number of times something happens per unit time. The two explanations combined mean the number of times the heart beats within a certain period of time, that is, how fast the heart beats within a certain period of time.

There are significant individual differences in the resting heart rate of normal adults, with an average of around 75 beats/minute (between 60-100 beats/minute). Heart rate can vary depending on age, gender, and other physiological conditions. The heart rate of a newborn is very high, reaching over 130 beats per minute. Among adults, women generally have a slightly faster heart rate than men. For the same person, the heart rate slows down when quiet or sleeping, and speeds up when exercising or emotionally excited. Under the influence of certain drugs or neurohumoral factors, the heart rate can speed up or slow down. People who regularly engage in physical labor and exercise usually have a slower heart rate. In recent years, a large-sample survey of healthy people in China found that the normal range of resting heart rate for Chinese men is 50-95 beats/minute, and for women it is 55-95 beats/minute. So, heart rate varies with age, gender, and health status.

Resting heart rate is a functional indicator that is easier to measure. It is usually measured by measuring the number of beats of the radial artery or carotid artery in 1 minute when the athlete is in a resting state.

Weightlifters have a higher resting heart rate, usually 50~70b/min, with a normal range of 50~90b/min. It slows down with the extension of training years and the improvement of training level. For weightlifters, the resting basal heart rate and the difference in strength reflex (the difference in heart rate from supine to standing position) can be used for monitoring. If the resting basal heart rate suddenly increases, it often indicates the presence of fatigue or illness, and special attention should be paid.
