What is the normal heart rate for a newborn baby?

The heart rate of a newborn is different from that of a normal adult and can change due to a variety of factors. If some newborns suffer from heart disease, the child's heart rate will be different from that of normal children. Therefore, parents must pay attention to their children's heart rate. If you find that your child has an abnormal heartbeat, seek medical attention immediately. So, what is the normal heart rate for a newborn?

The younger the age, the faster the heart rate. The heart rate for newborns is 120-140 beats/minute, 100-120 beats/minute for 2-3 years old, 80-100 beats/minute for 4-7 years old, and 70-90 beats/minute for 8-14 years old. Crying and fever increase the heart rate. When the body temperature rises by 1°C, the heart rate increases by 10-15 beats/minute.

The younger the child, the faster the breathing. The respiratory rate of newborns and children under 3 months old is about 45-50 times/minute, and then gradually slows down with age, reaching 20 times/minute at 10-14 years old.

1. Arrhythmia causes hemodynamic changes due to too fast or too slow heart rate and uncoordinated atrioventricular contraction. The extent of the impact on hemodynamics depends on whether the heart is normal and its compensatory function.

2. Children's breathing rate is easily affected by many factors, such as: emotional fluctuations, crying, physical activity, increased body temperature, anemia, respiratory, circulatory, nervous and other system diseases can all cause breathing to speed up or slow down.

The normal respiratory and heart rate values ​​of infants and young children fluctuate within a range and are not completely fixed. If parents discover during a physical examination that their baby's breathing and heart rate exceed normal levels, they should immediately inform the doctor to see if the baby has heart disease. If the baby has arrhythmia or multiple heart diseases, they should seek treatment immediately.
