Whether the heart rate 106 is high depends on whether the person is an adult or a child; if it is an adult, it is a little faster, and if it is a child, it is normal.
The normal resting heart rate in adults is 60-100 beats per minute, below 60 beats per minute is considered bradycardia and above 100 beats per minute is considered tachycardia. In children, the heart rate is usually faster, and the younger the child, the faster the heart rate. Tachycardia is usually associated with hyperthyroidism, anemia, or arrhythmia.
In children, a heart rate of 106 beats per minute is normal, but in adults, thyroid function and an ambulatory electrocardiogram (ECG) are recommended to check for hyperthyroidism or tachyarrhythmia. In addition, blood tests can be performed to see if there is anemia.
If you feel unwell, go to the hospital for treatment to avoid delay.
