the calculator permits the user to determine heart rate for diagnosis of tachycardia and bradycardia.

For an adult(age 18 and over), a normal heart rate ranges from 60 to 100 beats per minute (bpm). Usually women's heart rate is between about 70-80 beats per minute. Children's heart rate varies with age. Healthy young adults, men and women being physically active and athletes who often have heart rates of less than 60 beats a minute can be normal. Heart rate varies significantly between individuals based on fitness, age and genetics.
