Heart Rate Monitor
We have carefully reviewed various heart rate measuring devices and have come up with our ultimate top 10 lists of the best heart rate monitors for 2021.
Read on to find out more!
Our top pick for the best heart rate monitor for 2021 is more of a smartwatch, but it is still one of the best wearable heart rate monitors out there. The Apple Watch Series 4 is an excellent smart fitness tracker and is the best one released by Apple, yet when it comes to health benefits and features.
It will accurately measure your resting heart rate, as well as keep track and alert you about the heart zones during workouts or intensive physical activity via its unique electrical and optical heart sensors.
The smartwatch by Apple also has the ability to detect and notify you if anything is wrong with your heart rate, including detection of atrial fibrillation (AF), which if not treated in time can lead to serious and even fatal outcomes.
The smart wearable heart rate monitor will also alert you when it detects that your heart rate is too low or too high suddenly. You will be notified that you may need to see a physician.
What makes this smart heart rate monitor unique is its capability to perform an ECG (electrocardiogram), although this feature is only available in the US yet. It works with the WatchOS 5.1.2 update for the smartwatch.
You need to activate the app on your phone and hold the Digital Crown on the face of the watch so that there is a complete electrical circuit in your body. As a result, the data from your ECG will be sent to the Health app on your iPhone. You can export the results as a PDF file, and you also can add notes to every ECG about the circumstances so that you can later show the log or the results to your doctor.
The fall detection feature on the Apple SmartWatch 4 is automatically set up for people over the age of 65. This is a safety feature that will alert your contacts or 911 in case you fall down suddenly with an emergency SOS.
This 4th generation Apple Watch is the largest one know, so it is easy to see, even by elderly people or those with impaired vision. The display is 30% larger than its predecessors, and the loudspeaker is 50% louder.
It is available in different color options and in 2 sizes – 40mm and 44mm. It has built-in GPS and cellular connectivity. The ticking Digital Crown has haptic feedback. The watch is fitted with a powerful S4 SiP and a 64-bit dual-core processor.
It has one of the best accelerometers and gyroscopes among all wearable smart health trackers. It is completely waterproof, so you can monitor your heart rate even when swimming or when it is pouring, and you are exercising outdoors.
The watch also features new hiking and yoga workouts, as well as advanced features for runners such as pace alerts and cadence. You can also set your goals, participate in monthly challenges, use the personalized coaching option, and set activity alerts for every day.
Thanks to the built-in cellular, you can take and make calls, use the watch as a walkie-talkie, stream your favorite music and use Siri without needing your phone. In fact, with the Apple Watch 4, you can leave your phone at home and feel safer than ever thanks to its unique sensors, alert features, and health monitoring options.
As you can see, the Apple Watch 4 is more like having your physician with you at all times, than like wearing a simple wearable fitness tracker. It is definitely a must-have for those of you who want accurate heart rate readings, notifications, and warnings when there is a problem with the heart rate as well as the unique opportunity to do an ECG on yourself anytime you feel funny or like something is wrong with your heart.
Our runner up is yet another smart wrist-based heart rate monitor that has an excellent heart rate reading function. This is the flagship fitness tracker of Garmin and is designed for professional or hardcore triathletes and athletes. Still, even if you are neither of those, you can take advantage of the multiple features of this amazing health and fitness tracker.
It is made of soft and comfortable silicone, weighs a mere 1.76oz, and is 0.5 x 1.8 x 2.1 inches in size, so you can wear it all day and all night comfortably, no matter whether you are exercising intensively or sleeping.
It has a built-in GPS, a barometer, electronic compass, and an altimeter. This watch will monitor and evaluate your training status and physical condition and will inform you if you can boost your performance or you are overdoing it a bit. This smart fitness tracker will also monitor your recovery, so you can prepare for your next race properly.
Since it is made for triathletes, it has a number of useful functions for swimming, running and cycling, including ground contact time, stride length, balance, and others.
The wrist heart rate monitor by Garmin is offered in several different color options, and can be paired with another one of our favorite products in this list – the Garmin HRM-Tri Heart Rate Monitor chest strap for even more accurate results and heart rate readings.
It has a long battery life, which can last for 2 weeks if you wear it in watch mode for 2 hours with the GPS on and up to 50 hours in the UltraTac mode.
You can connect it to your smartphone, upload to Garmin Connect, share your activity with your friends, get call and message notifications, and others.
With a smartwatch like the Garmin Forerunner 935, you will have an accurate heart rate monitor on your wrist at all times, and if you add a chest strap, you can add functions like a heart rate variability stress test or a lactate threshold.

Features to look for when buying a heart rate monitor
The type of device
You should first pick the type of heart rate monitor which will suit your needs. You can get a wearable heart rate monitor if you want to track and log your heart rate readings and get alerts if something worrying is going on with your pulse. On the other hand, you can pick a traditional heart rate monitor that you can use in the comfort of your home, and which, too, will log your readings and notify you if your heart rate is too slow or too fast.
Optical vs. ECG monitors
The electric heart rate sensors will measure the electric signals which control how your heart expands and contracts. The optical heart rate sensors will shine a special LED light through your skin and then will record any changes in the blood flow. Many of our top picks, which have optical sensors, have additional electrodes and devices which ensure that the sensor is properly positioned and that it reaches deeper under the skin for more accurate readings.
ECG and Heart rate variability
As you can see from our top 10 list of the best heart rate monitors for 2021, some will measure your HRV which means measuring the millisecond deviations of your heartbeat, which is amazingly useful for balancing your training, resting, work and family life properly.
The devices which offer an ECG function, like the Apple Watch 4 can actually be life-saving devices, as they can detect the early signs of serious and even fatal conditions like Atrial fibrillation, or other irregularities in the heart rate which may require immediate care and attention.
Choose a heart rate monitor that can connect to the device you already have and intend to use for tracking, storing, and analyzing your heart rate readings and logs. This can be your smartphone, a smartwatch, a chest strap, or any fitness tracking device. Make sure that the heart rate monitor of your choice has the proper connectivity options in order to be able to take advantage of all of its functions.
Finding a reliable heart rate monitor is essential both for athletes and for all other people. Keeping an eye on your heart rate will help you improve your performance when training and recovering, and will also keep you informed about your current heart health and alert you if there is something wrong with your heart rate.
Hopefully, you have found that perfect heart rate monitor for your needs in our top 10 list.
We wish you good luck with your new device, and sincerely believe that it will serve the purpose you are buying it for!
