High heart rate:

The heart rate is a term used to describe the frequency of the cardiac cycle. It is considered one of the four vital signs. Usually it is calculated as the number of contractions (heart beats) of the heart in one minute and expressed as "beats per minute" (bpm). Heart for information on embryo fetal heart rates. When resting, the adult human heart beats at about 70 bpm (males) and 75 bpm (females), but this rate varies between people. However, the reference

range is nominally between 60 bpm (if less termed bradycardia) and 100 bpm (if greater, termed tachycardia). The Resting heart rates can be significantly lower in athletes, and significantly higher in the obese.
The body can increase the heart rate in response to a wide variety of conditions in order to increase the cardiac output (the amount of blood ejected by the heart per unit time). Exercise, environmental stressors or psychological stress can cause the heart rate to increase above the resting rate. The pulse is the most straightforward way of measuring the heart rate, but it can be deceptive when some strokes do not lead to much cardiac output. In these cases (as happens in some arrhythmias), the heart rate may be considerably higher than the pulse.

Heart rate variability

Heart rate variability is the variation of beat-to-beat intervals. A healthy heart has a large HRV, while decreased or absent variability may indicate cardiac disease. HRV also decreases with exercise-induced tachycardia. The One aspect of the heart rate variability can be used as a measurement of fitness, specifically the speed at which one's heart rate drops upon termination of vigorous exercise. The speed, at which a person's heart rate which returns to resting, is faster for a fit person than an unfit person. A drop of 20 beats in a minute is typical for a healthy person.

Heart rate abnormalities:

Tachycardia
The Tachycardia is a resting heart rate more than 101 beats per minute.
Bradycardia
The Bradycardia is defined as a heart rate less than 60 beats per minute although it is seldom symptomatic until below 50 bpm. Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it.

Low heart rate:
Low heart rate means that the heart is beating too slowly usually less than 60 beats per minute. It is important to realize that for some people with healthy hearts, a rate below 60 beats per minute may be normal. After all, our heart rates may dip...
