How Does a Heart Rate Monitor Work?

A heart rate monitor is a device that you wear to show your heart rate continuously as you engage in exercise. Electrode sensors transmit data to a receiver display such as a fitness wearable, watch, or phone app. The receiver displays the number as beats per minute.

Simple designs only show the heart rate at a given time. Intricate designs not only show the heart rate but can also record time, show an average rate and maximum rate for a specific exercise period. Some have alarms when the user reaches or exceeds a pre-set target heart rate zone.

Key Features

Recovery Heart Rate

Advanced heart rate monitors have the ability to measure resting heart rate. It shows the time required for the heart to return to a normal, resting stage. It is an essential indication of heart health, and people that engage in high-intensity workouts find it extremely important.

Pulse Monitoring

Pulse monitors work by detecting the pulse. You can easily place a finger or two on the sensors for automatic reading. However, the rate might not be reliable, especially with cold fingers.

Heart Rate Zones

Some monitors allow you to set one or several target rate zones. These heart rate zones depend on the specific workout you intend to engage in. The time in the target zone will measure the amount of time you spend exercising within the specified target zone.

Sport Watch

Some heart rate monitors feature digital calendars, clocks, alarms, and timers. These features make the monitor more of a sports watch but useful for people that need such functions when working out.

Distance and Speed Monitoring

When exercising, some monitors calculate the speed and the distance you cover. These features rely on a GPS receiver in outdoor environments for accuracy. Indoor workouts rely on a footpad together with an accelerometer to gauge the length of strides.

Calorie Counts

This feature in some monitors displays the number of calories you burn during workouts. It is an important feature, especially for people on a weight loss journey that need to track their calorie deficit.

Lap Times and Stopwatch

Recent models of heart rate monitors measure the time in laps. Some feature a lap button to measure the change in pace during exercise.


This feature is common among most fitness trackers. It allows a wireless connection to your smartphone for easy control of phone features. With this feature, you can easily connect to fitness apps, play music, text without having to take out your phone from your pocket.

Code Transmitter

For chest strap designs a code transmitter encrypts between the sensor and the wrist unit. This activity prevents any communication between the signals of other devices on the people around you.


The accuracy of a heart rate monitor depends on the specific type. Chest straps are preferable among athletes because they display more accurate data. There are a few reasons why chest straps are more reliable than the wrist-mounted type, one being they are worn close to the heart [1].

A chest strap captures a stronger heartbeat compared to the wristband type. A good example to explain the accurate readings of chest straps is how doctors use ECG machines. They usually place the sensors on specific parts of the body, with most around the chest area. This allows doctors to assess the electrical activity of the heart.

Following this example, a chest strap design simplifies the method for convenience and comfort.

Another reason why chest straps are accurate is they leave no room for user error. When you buy the right size of a chest strap, it is less likely to wear it loosely as it would fall to the waist.

Also, the electrodes are on the straps, so you do not have enough room to move the strap around. Somstraps have one central electrode near the chest bone, while others have two that lay on the rib cage. There is little flexibility with wearing chest straps, and while this can make you uncomfortable, it explains why they are accurate.

When it comes to using wrist-mounted fitness trackers, a little movement of the device can alter the readings. For example, if you are doing a high-intensity workout, the monitor can shift around, too low, or too high on your wrist. They are much comfortable to wear than chest straps, but with the movement, they cannot guarantee accuracy all the time. 

If the wristband is tight, then movement should not be much of an issue. A comfortable fit is essential; however, you need to understand how tight it can be to affect functionality. If the band is too snug on the wrist, it could interfere with blood flow.

Although the monitor can pick up signals better, it cannot be accurate because blood will not flow naturally to your wrist. Again, if it is too loose, then space and air can affect how the monitor captures the heart rate. The idea is to ensure it fits snugly enough to move around but not too tight to obstruct blood flow.

Types of Heart Rate Monitors

Fitness heart rate monitors come in two types.


Wristwatch monitors are available in two main types. The simple model only functions if you touch the device to read the heart rate at a specific time. These work just like regular wristwatches; they are small and compact. Although these are good for reading the rate once in a while, they do not give you constant readings.

The other type, which is most common among fitness enthusiasts, gives continuous heart rate readings. Like a regular watch, this type is small, compact, and comfortable to wear. However, you need to place such a watch above the wrist bone and fit it snugly for effective use.

The continuous reading wristwatch is ideal for any kind of workout, as long it fits correctly. Since they are more convenient than other types, they come at a price. There are different brands, and the features vary from one brand to another

Chest Strap

The chest heart rate monitor is the most accurate type. Because it is placed very close to the heart, the monitor picks up signals better for accurate results. The monitor comes as a strap that you fit on the chest region. It has electrodes or infra-red sensors that link to the display unit. In most cases, the display unit is the receiver end of the device, usually on the wrist.

The display unit will beep if the heart rate goes above a pre-determined limit. It is simple to use and works perfectly for regular fitness enthusiasts and athletes.

The best feature of this type is that it delivers continuous heart rate readings. Although it can be uncomfortable to wear for long hours, it does not hinder movements and shows the readings automatically.


What Is the Most Accurate Heart Rate Monitor?

The type, fit, and functionality of a heart rate monitor affects its accuracy. Generally, chest straps are more accurate than wristwatch monitors because they are located close to the heart. Also, they have little or no room for user error to interfere with the results.

How to Pair Polar Heart Rate Monitor With Watch?

According to the Polar website, you can easily pair the sensor with your watch. First, you need to wear a moistened sensor. On the watch, open ‘general settings,’ ‘pair and sync,’ ‘pair sensor,’ and press ‘OK.’ Next, touch your sensor with the watch and wait for a while. Once the sensor is found, and the device ID found, press ‘OK’ to start pairing.

The Bottom Line

You cannot overlook the importance of heart rate monitors. It is not only useful to measure your heart rate at a given time but also helps you alter the activity to suit your lifestyle. The above heart rate monitors are ideal, whether you are an avid athlete or a fitness enthusiast. With an understanding of the features to look for, you can easily select a design that works best for you.
