Patient's question:
My baby just started attending kindergarten this year. Since it's their first time experiencing group living, they often get infected with colds. Yesterday, my baby had a slight fever due to a cold, and I noticed that their pulse and heartbeat were both very fast when they had a fever. Here, I would like to consult a doctor: what could be the reason for a child's fast pulse and heartbeat when they have a fever?Doctor's answer:
Under normal circumstances, a slight increase in body temperature can lead to an increase of 10 beats in heart rate and pulse. Therefore, it is normal for a baby's pulse and heartbeat to become faster after a fever. If the fever subsides and the pulse and heartbeat return to normal, you can focus on careful observation and resolution. If the fever subsides but the pulse and heartbeat remain slightly fast, it is necessary to rule out other diseases that may have caused it. It is recommended to seek medical attention for a thorough examination and treatment. In daily life, pay attention to drinking more water, avoiding cold exposure, and avoiding consuming spicy foods.
