Polar OH1+ is an optical heart rate monitor that combines versatility, comfort and simplicity. You can use it both as a standalone device and pair it with various fitness apps, sports watches and smart watches, thanks to Bluetooth and ANT+ connectivity.

A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as electrocardiography (ECG or EKG).

Medical heart rate monitoring used in hospitals is usually wired and usually multiple sensors are used. Portable medical units are referred to as a Holter monitor. Consumer heart rate monitors are designed for everyday use and do not use wires to connect.

Early models consisted of a monitoring box with a set of electrode leads which attached to the chest. The first wireless EKG heart rate monitor was invented in 1977 by Polar Electro as a training aid for the Finnish National Cross Country Ski team. As "intensity training" became a popular concept in athletic circles in the mid-80s, retail sales of wireless personal heart monitors started in 1983.[1]

Modern heart rate monitors commonly use one of two different methods to record heart signals (electrical and optical). Both types of signals can provide the same basic heart rate data, using fully automated algorithms to measure heart rate, such as the Pan-Tompkins algorithm.[2]

The electrical monitors consist of two elements: a monitor/transmitter, which is worn on a chest strap, and a receiver. When a heartbeat is detected, a radio signal is transmitted, which the receiver uses to display/determine the current heart rate. This signal can be a simple radio pulse or a unique coded signal from the chest strap (such as Bluetooth, ANT, or other low-power radio links). Newer technology prevents one user's receiver from using signals from other nearby transmitters (known as cross-talk interference) or eavesdropping. Note, the older Polar 5.1 kHz radio transmission technology is usable underwater. Both Bluetooth and Ant+ use the 2.4 GHz radio band, which cannot send signals underwater.

More recent devices use optics to measure heart rate by shining light from an LED through the skin and measuring how it scatters off blood vessels. In addition to measuring the heart rate, some devices using this technology are able to measure blood oxygen saturation (SpO2). Some recent optical sensors can also transmit data as mentioned above.

Newer devices such as cell phones or watches can be used to display and/or collect the information. Some devices can simultaneously monitor heart rate, oxygen saturation, and other parameters. These may include sensors such as accelerometers, gyroscopes, and GPS to detect speed, location and distance.[3] In recent years, it has been common for smartwatches to include heart rate monitors, which has greatly increased popularity.[4] Some smartwatches, smart bands and cell phones often use PPG sensors.[5]

The newer, wrist based heart rate monitors have achieved almost identical levels of accuracy as their chest strap counterparts with independent tests showing up to 95% accuracy, but sometimes more than 30% error can persist for several minutes.[9] Optical devices can be less accurate when used during vigorous activity,[10] or when used underwater.

Currently, heart rate variability is less available on optical devices.[11] Apple introduced HRV data collection to the Apple Watch devices in 2018.[12] Fitbit started offering HRV monitoring on their devices starting from the Fitbit Sense, released in 2020.[13]

HR monitors come in two types, as George Sopko, MD, MPH, Medical Officer and Program Director of the National Heart, Lung, and Blood Institute (NHLBI) explains. Basic models check your HR range, while advanced models provide detailed heart rhythm information and can indicate potential cardiovascular issues.

Remember that even though some smartwatches can track your heart rate, they may not be as effective as a dedicated heart rate monitoring device. Experts say that the type of smartwatch you use can impact data reliability, especially during arm-intensive exercises, and accuracy can decline with higher activity levels or sweating.

If a chest strap is out of the question because you need to see your metrics in real time and glance at them during the day, the Forerunner 265 is a multisport watch that can deliver reliable heart rate metrics during workouts, and even when you head to bed.

When Wahoo launched its Tickr X chest strap back in 2020, it clipped on from the front (unlike most monitors) and served up practical extra metrics about your running and cycling sessions. The Trackr is a new replacement to the Tickr X, but unlike the previous best buy, Wahoo has stripped back the extras, dropped the price, and made sure you never have to deal with another battery.

While some try to dispute it, the Apple Watch remains the standout smartwatch. Part of its mass appeal is its ability to take similar sensors found inside rival smartwatches, but deliver a more compelling level of accuracy and insight. The result is a watch that makes a fine training companion and also a potentially life-saving wearable.

It is also one of the best sleep trackers in the business. The app is extremely comprehensive, and while it can't quite replace a sports watch, the Whoop will reliably capture your heart rate variability measurements and help you better understand the importance of effort and recovery. Just be prepared to pay the pricey monthly ($16/16) or annual subscription to make the most of it.

Why would you want a heart rate monitor? What kind of information do you need to see, and when and how will you wear the device? Answering these questions will help you get a heart rate monitor that not only delivers wearability, accuracy, and value, but ensuirte you strap it to the ideal part of your body.

This is a fitness metric that has been around for a long time and has been rebranded or renamed by some smartwatch makers. It wants to tell you how strong your cardiovascular fitness is, and provide a useful indicator of your endurance to sustain intense exercise for long periods. The term VO2 Max stands for maximum rate of oxygen your body can consume during exercise. Seeing a high VO2 Max score is a sign of a boost in the rate of oxygen you can consume. Calculating this accurately is done in lab conditions, so heart rate monitors and watches will use their own algorithms to replace some of that lab testing to provide a simpler way to present that metric.

TICKR FIT heart rate armband uses optical heart rate technology to provide accurate heart rate and calorie burn data in the most comfortable form factor yet!
