What heart rate is recorded as tachycardia for a 2-year-old patient?

In a 2-year-old patient, tachycardia is defined as a heart rate that exceeds the normal resting rate for their age group. For children, the typical resting heart rate ranges from approximately 70 to 110 beats per minute.

When considering the threshold for tachycardia, a heart rate above 110 beats per minute is generally recognized as tachycardic in young children. A heart rate of 150 beats per minute clearly exceeds this threshold, categorizing it as tachycardia. This elevated rate could indicate a physiological response to a variety of factors, such as fever, dehydration, anxiety, or underlying cardiac issues.

By contrast, the other heart rates fall within the normal range for a 2-year-old. For example, rates of 80, 110, and 85 beats per minute align with what could be expected from a resting heart rate, particularly considering variances due to activity levels and the child's emotional state. Thus, only a heart rate of 150 beats per minute is classified as tachycardic for a 2-year-old child.
