The resting heart rate refers to the heart rate when a person is relaxed. While a normal heart rate does not guarantee that a person is free of health problems, it is a useful benchmark for identifying a range of health issues. The heart is a muscular organ in the center of the chest. When it beats, the heart pumps blood containing oxygen and nutrients around the body and brings back waste products.
A healthy heart supplies the body with just the right amount of blood at the right rate for whatever the body is doing at that time. For example, being frightened or surprised automatically releases adrenaline, a hormone, to make the heart rate faster. This prepares the body to use more oxygen and energy to escape or confront potential danger. The pulse is often confused with the heart rate but refers instead to how many times per minute the arteries expand and contract in response to the pumping action of the heart.
The pulse rate is exactly equal to the heartbeat, as the contractions of the heart cause the increases in blood pressure in the arteries that lead to a noticeable pulse. It is important to identify whether your heart rate sits within the normal range. If disease or injury weakens the heart, the organs will not receive enough blood to function normally. The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and beats per minute bpm.
The following is a table of normal resting heart rates at different ages according to the NIH:. The resting heart rate can vary within this normal range.
It will increase in response to a variety of changes, including exercise, body temperature, emotional triggers, and body position, such as for a short while after standing up quickly. When training for fitness, it is important not to put too much strain on the heart.
However, an individual needs the heart rate to increase while exercising to provide more oxygen and energy for the rest of the body. While the heart rate increases as a result of physical activity, an overall decrease in target heart rate is possible over time.
This means that the heart is working less to get the necessary nutrients and oxygen to different parts of the body, making it more efficient. Cardiovascular training aims to reduce the target heart rate.
The ideal target heart rate reduces with age. It is also worth noting the maximum heart rate. This demonstrates the full capability of the heart, and it is normally reached through high-intensity exercise. The American Heart Association AHA states that the maximum heart rate during exercise should be roughly equal to bpm minus the age of the person.
As the body of each individual will react to exercise differently, the target heart rate is presented as a range known as the target heart rate zone. The following table shows the appropriate target heart rate zone for a range of ages. It is recommended that people exercise regularly to work towards a healthy target heart rate. The AHA recommends the following amounts and levels of exercise per week:.
The speed of the heart is not the only factor to bear in mind when considering its health. The rhythm of the heartbeat is important too. The heart should beat with a steady rhythm, and there should be a regular gap between beats.
The muscle has an electrical system that tells it when to beat and push blood around the body. A faulty electrical system can lead to an abnormal heart rhythm. It is normal for the heart rate to vary throughout the day in response to exercise, anxiety , excitement, and fear. However, a person should not normally be aware of their resting heartbeat.
If you feel that your heart is beating out of rhythm, too fast, or too slow, speak to a doctor about your symptoms. An extra beat is called an ectopic beat. Ectopic beats are very common, usually harmless, and do not often need treatment. People concerned about palpitations or ectopic beats should speak to your doctor who will be able to carry out an electrocardiogram ECG to assess the heart rate and the rhythm.
There are many different types of abnormal heart rhythm. The type depends on where in the heart the abnormal rhythm starts, and whether it causes the heart to beat too fast or too slow. The most common abnormal rhythm is atrial fibrillation.
This replaces the normal heartbeat with an erratic pattern. A fast heart rhythm is also known as a tachycardia , and can include:. Slow heart rhythms such as atrioventricular AV heart block , bundle branch block, and tachy-brady syndrome are called bradycardias. While exercise is important for promoting a low and healthy heart rate, there are several other steps a person can take to protect their heart health, including:.

Fast facts on the heart rate The heart rate measures the number of times the heart beats per minute. After the age of 10 years, the heart rate of a person should be between 60 and beats per minute while they are resting. The heart will speed up during exercise. There is a recommended maximum heart rate that varies depending on the age of the individual. It is not only the speed of the heart rate that is important. The rhythm of the heartbeat is also crucial, and an irregular heartbeat can be a sign of a serious health condition.
