Final answer:
The normal pulse rates vary by age, with adults having a resting heart rate of 60-100 bpm, infants around 120 bpm, and children aged 12-14 years at 60-80 bpm. Abnormal heart rates can indicate health problems, and athletes often have lower heart rates.
Step-by-step explanation:
The normal pulse rate for different age ranges in beats per minute (bpm) varies. For adults, a normal resting heart rate (HR) is in the range of 60-100 bpm.
Infants, particularly newborns, have a higher resting HR, typically around 120 bpm, whereas older children, such as those aged 12-14 years, generally have a pulse rate close to that of adults, which could be slightly lower, thus for children aged 12-14 years, it's often between 60-80 bpm.
Disorders surrounding abnormal heart rates include bradycardia, a condition where the resting rate drops below 60 bpm, and tachycardia, where the rate exceeds 100 bpm. Athletes often have lower HRs, and this can be considered normal if they are not experiencing any adverse symptoms. However, heart rates that deviate significantly from the normal range can indicate underlying health issues and warrant further medical examination.
