What is a heart Stroke volume in child?

Stroke volume in children varies depending on age and body size. Here are the average stroke volume values for different age groups:

Newborn (0-1 month): 2-3 mL

Infant (1-12 months): 4-6 mL

Toddler (1-3 years): 7-9 mL

Preschooler (3-5 years): 10-12 mL

School-age child (6-12 years): 13-15 mL

Adolescent (13-18 years): 16-18 mL

These values can vary depending on individual factors such as heart rate, blood pressure, and body size. It's important to note that stroke volume is just one component of cardiac output, which is the amount of blood pumped by the heart per minute. Cardiac output is calculated by multiplying stroke volume by heart rate.

If you have concerns about your child's heart health, it's best to consult with a pediatrician or pediatric cardiologist. They can assess your child's individual情況 and determine if there are any underlying issues.
