Patient's question:
The baby is one and a half years old. Today, using an electronic blood pressure monitor, the heart rate was 136-137 beats twice. In good spirits. Loves to play, breathes a bit heavily during intense exercise. Can run around for 10 minutes. Temperature under the armpit is 37.2 degrees. Two days ago, the baby received the DTP and MMR vaccines. The heart rate measurement was taken when the baby was at rest. Besides viral myocarditis, what other conditions could cause the baby's heart rate to be elevated?Doctor's answer:
Hello, tachycardia can be caused by physiological factors in addition to pathological ones. Many people only know that a normal heart rate for adults is 60-100 beats per minute, but this is just the average for adults. The average heart rate for children aged 1-3 is about 127 beats per minute, with lower rates around 80 and higher rates around 166. Therefore, for a 1.5-year-old child, a heart rate of 136 is normal.
