High heart rate:
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:
The Tachycardia is a resting heart rate more than 101 beats per minute.
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.

A heart rate monitor is an electronic device that allows a user to monitor heart rate while engage in sports like swimming, or running and exercising. It normally has two parts a chest strap and a wrist receiver. Wrist receiver has a watch....
Heart Rate Monitors -
What are Heart Rate Monitors? A device usually worn like a watch and consists of a chest strap and a wrist receiver, used to monitor the heart rate during exercise. The reading shows the hearts beats per minute. They are used as a tool for...
Heart rate variability:
Heart rate variability or in short HRV is a term coined for measure of variations in the heart rate. Heart rate variability is more often than not calculated by analyzing the time series of beat-to-beat intervals from ECG or arterial pressure...
The term used to describe the frequency of the cardiac cycle is Heart rate. Heart rate is considered to be one of the four vital signs. Generally it is calculated as the number of contractions, which are called heart beats, of the heart in one...
Heart Rate Monitor Training:
rate whilst exercising. The use of an HRM to set exercise intensity is based on sound physiological principals - as the work increases, oxygen consumption and heart rate increases in a linear relationship until near maximal intensities. Once it...
Heart rate monitor watches:
wristwatches were developed, and luminous hands and markers were developed. Men tended to regard the heart rate monitor watch as effeminate. So, the vintage Rolex men's watch is a relatively rare timepiece. As demand for heart rate monitor watches...
Heart rate reaction in comparison to sugar:
Every time you swallow a bite of sandwich or slurp a smoothie, your body works hard to process the nutrients you've eaten. Long after the dishes are cleared and the food is digested, the nutrients you've taken in become the building blocks and fuel...

Heart Rate and heart rate monitor: The number of times the heart beats or contracts in one minute is called as the heart rate. It is measured in beats per minute (bpm). Often known as pulse, it is usually measured to obtain a quick evaluation...
Rapid heart rate:
Rapid heart beat in medical terms known as tachycardia or fast heartbeat. The heart normally beats less than 100 times per minute in adults and slightly more than 100 times in children. A rapid heart rate is defined as the heart rate that is faster...
