Which age group has a maximum heart rate of 180 bpm?

Explanation:
Newborns can push their heart rate to very high levels to meet metabolic demands, especially during crying or distress. Their stroke volume is small, so to maintain adequate cardiac output (CO = heart rate × stroke volume), the heart rate rises quickly. Around 180 beats per minute is a typical ceiling seen in newborns during activity or stress, which is why this age group fits the description. The common rule of 220 minus age isn’t reliable for infants, so it doesn’t apply here.
