Having a slow heart beat isn't always a health problem. In fact, it's normal for some people, especially healthy, young individuals. The medical term for this condition is bradycardia. It’s defined as having a heart rate of less than 60 beats per minute, according to MayoClinic.com.

It's easy to feel panicked when you experience a fast or irregular heart rate, especially when it's coupled with other symptoms such as feeling lightheaded. Symptoms affecting the heart warrant medical attention, particularly if they happen suddenly.

The wide range of medical information available online has made it easy for you to take various conditions and symptoms and determine exactly what's wrong in your body. This is true for people with an elevated heart rate and episodes of burping, which have a minor relationship through shared risk factors.

Your heart rate, or the number of times your heart beats within one minute, is a good measure of both cardiovascular fitness and workout intensity.

Your circulatory and respiratory systems function to supply your body with blood and oxygen through all activity levels, from rest to physical exertion. The amount of blood circulated throughout your body is based on two measurable components -- stroke volume and heart rate.

Your breathing rate is primarily regulated by neural and chemical mechanisms. Respiration is controlled by spontaneous neural discharge from the brain to nerves that innervate respiratory muscles. The primary respiratory muscle is the diaphragm, which is innervated by the phrenic nerve.

The rate at which your heart beats during exercise is an excellent indicator of the intensity of the activity. Monitoring your heart rate helps you determine if you are working hard enough to burn fat or if you are working too hard -- which reduces fat burning.

Your heart rate and metabolic rate are two very different things. When a doctor takes your pulse, he is measuring your heart rate, or how fast your heart is beating. Your resting metabolic rate calculates how fast you burn energy when you are inactive. Both measurements can help determine overall fitness and health.

A treadmill maximum heart rate test is just what the name indicates; the test, performed on a treadmill, is designed to increase the exerciser’s heart rate to its maximum. The procedure is also known as a “stress test” and that label is also accurate, because the test does stress your heart and push it to its limit.

You know that exercise is supposed to be good for your health, and you have undoubtedly tried to get into a regular routine. But when exercise leaves you with a racing pulse and unable to catch your breath, it's hard to stick with the program.

Your heart rate is a term that describes how fast or slow your heart beats every minute. If your heart beats faster than normal, you may be diagnosed with medical conditions such as hypertension. Your heart is made up of four chambers, each of which needs to work effectively and in synchronization for optimal function.

Your maximum heart rate is an estimate of how many times your heart should beat per minute at its maximum rate. If you exercise at or above your maximum heart rate, you can face certain health consequences. Speak to your doctor before starting an exercise program that uses your heart rate as a guide.
