Guide to DIY Heart Rate Monitors (HRMs) & Handheld ECG Monitors (Part I)

Consumer Heart Rate Monitors (HRMs) and Handheld ECG monitors

by Steve S. Ryan, PhD, Last updated: July 9, 2018

Atrial Fibrillation patients sometimes want to monitor their heart rate and pulse when exercising or when performing physically demanding activities (i.e., mowing the lawn, climbing stairs, loading and unloading equipment, etc.). A consumer ‘DIY” heart rate  monitor (HRM) or Handheld ECG monitor may meet this need.

Not to be Confused with Optical Fitness Wristbands

The HRM sensors/monitors in this article work by being in contact with the skin. Don’t confuse these with fitness bands like Fitbit that use an optical sensor to shine a light on your skin illuminating your capillaries to measure your pulse (most accurate for a resting heart). To read a comparison test by Tom’s Guide, see Who Has The Most Accurate Heart Rate Monitor? It’s All About Accuracy (Spoiler alert: top rated was the Polar T7 chestband). 

 Consumer HRMS

We’ve sorted through the plethora of Heart Rate Monitors (HRM) products and brands and have recommend products in a range of prices and with a range of features.

Consumer, DIY or ‘Sport’ Heart Rate Monitors (HRM) are designed for runners and other recreational athletes to collect helpful data for lifestyle changes and training goals (pace, distance, heart rate, pulse, etc.).

Heartbeat sensors are either attached to a chest band (or arm band) or built-in to wearable technology and paired with a wireless link to a wrist watch or app-enabled smartphone. HRMs are available from sporting goods stores and online from and other sites.

For our quick start list go to Steve’s Top Picks: DIY Heart Rate Monitors for A-Fib Patients on

The Gold Standard brand for HRMs is Polar. (The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team.) You can view the extensive range of Polar products at their website,

Other companies offering consumer ‘Sport’ Heart Rate Monitors include Timex, Garmin, Acumen, Nike, and Cardiosport plus a host of others if you shop around.

To learn how HRMs work, recording capabilities and how they can help A-Fib patients monitor their heart rate, see Part 2 of this article: DIY Heart Rate Monitors: How They Work For A-Fib Patients (Part II).

We’ve Done the Hard Lifting for You

To help you sort through their extensive offerings, I narrowed down the choices to a few basic and advanced wristwatch models, Bluetooth models, and the newer wearable technology each in an array of price points.

Polar FT1 HRM with chest band at

Polar FT1 HRM with chest band

Wrist Watch Monitors with Chest Band

Consisting of two components, these HRMs use sensors attached to a heart rate strap that wraps around the chest and sends a wireless signal to the wrist unit. Some models connect with compatible gym equipment using GymLink. (More features = higher prices.) A few to consider:

♥  Polar FT1 Heart Rate Monitor Watch (about $28-$42)
♥  Polar FT7 Fitness Heart Rate Monitor Watch ($69)
Polar RS300X Heart Rate Monitor (about $88)
♥  Polar V800 GPS Sports Watch & Activity Tracker (about $360)

Bluetooth App-Enabled Sensors for Smartphones

Smartphones are ubiquitous. For many, their smartphone is an essential part of their standard daily gear. So, it’s no wonder that a smartphone can replace the wrist watch monitor.

Today, you can use Bluetooth technology to send the signal from your heart rate sensor to a receiver in an app-enabled smartphone. Here are a couple to consider:

♥  Polar H7 Bluetooth Smart Heart Rate Sensor (about $49)
♥  60beat BLUE Heart Rate Monitor for iPhone and most newer Androids (about $35)
♥  Jarv Premium Bluetooth® 4.0 Smart Heart Rate Monitor for Android Devices (about $28)
♥  Scosche RHYTHM+ Heart Rate Monitor with Armband (about $80)

Wearable Technology with Wireless Sensors

“Wearable technology” offers a new option for those who find a chest strap uncomfortable or chafing. With these workout clothes, sensors are built-in—to a women’s jogging bra or men’s t-shirt, for example. Note: these items replace the chest band only. (There are also HRM caps, headbands and visors). Here are a few examples:

Wearable technology

Wearable technology

♥  Weartech Men’s Gow Smart Sports T-Shirt (Intergrated Cardiac Sensors) ($24-59)
♥  Adidas Men’s Heart Rate Monitoring Techfit Shirt ($59)
♥  Weartech Women’s Gow Smart Sports Bra (Intergrated Cardiac Sensors) ($39-79)
♥  Adidas Heart Rate Monitoring Smart Bra – seamless – white or black (about $59)

Unless sold as a set, you still need a Heart Rate sensor to snap on to the front of the garment (if you are replacing a chest band, you may be able to reuse the sensor) and you will need something to receive the signal—a wrist watch monitor or app-enabled smartphone.

 Real-Time ECG Monitors

See “Comparison of handheld, 1-lead/channel ECG / EKG recorders” by James W. Grier, for an extremely detailed report of 14 Handheld ECG Monitors

This category of consumer monitors has been growing of late with some models having only limited track records. Going beyond just monitoring your heart rate, these units capture data and display it as an ECG (EKG) in real time.

With prices ranging from $99 to $300 (and up), you need to consider size (portability) and ease of use compared to price. Again, I’ve selected a few handheld ECG monitors from the plethora of choices.

Handheld 12-Lead ECG Monitor CMS-80A (FaceLake or Contec Medical Systems)

Facelake Hand-Held Single Channel ECG, ECG 80A Link

Facelake Hand-Held ECG 80A

Review by Ed Webb

Note: Read about how Tom Burt used the CMS-80A in his Personal Experience story. He writes, “This came in very handy as a way to inform my EP when I did get out of rhythm. This was done by faxing him a strip of the printout.”

The Contec CMS-80A is a single channel, 12 lead monitor which can provide data via one of three ways: on the unit display, via the thermal printer internal to the unit, or via a USB connection to a PC. The printout from the unit offers the easiest and most accurate means to view lead output. While you can view lead output on the display, you will find that it is not to the same level of detail as the printout.

Like most normal ECG monitors, 10 electrodes are attached to the body as follows: 6 suction cup leads to the chest and 4 alligator clip leads to the arms and legs. The unit does not rely on the normal press-on style contacts but rather takes a simpler approach with its reusable contacts. Personally, I [Ed Webb] wasn’t too impressed with the suction cup style contacts as they feel funny and leave a mark as if you had been attacked by an octopus. But they seemed to do the job. The alligator clips, while funky, were quick and easy to attach.

The waveforms presented are not what you would expect from an ECG in your cardiologist’s office, but they can provide the simple basics to make a quick determination whether you are in A-Fib. In particular, by examining the output from Lead II, or perhaps Lead aVF, you can quickly observe the absence of a P wave—one sign that you may be in A-Fib. Additionally, examining R-R intervals and whether they are uniformly spaced can be another means to aid in that determination.

From a practical perspective, it could be that you choose to only attach the alligator leads to your arms and legs and forego using the chest leads. You will obviously not have the data from the chest leads (V1 to V6), but that information may not be needed for A-Fib purposes.

FDA-approved. For more info and to see what the display looks like, visit the Contec product information page. The CMS-80A (ECG-80A) can be purchased directly from and other locations online ($299-$380).

 Remote Smart Monitors

MyPulse Provides Email or Text Message Alerts

Are you worried about a relative in A-Fib whom you can’t be with all the time? There is a long range heart monitor your relative can use which will transmit to you if he/she goes into A-Fib or exceeds a normal heart rate.

MyPulse by Smart Monitors link

MyPulse (home model) by Smart Monitors

If you have a need to monitor a relative’s or friend’s heart rate or want to know if your relative or friend has gone into A-Fib, MyPulse by Smart Monitors, Inc. has a solution for you. (Prices range from  $149 – $495.) This is a practical alternative to the expense of a medical monitoring service if you are just interested in simple heart rate data. Obviously, if there are medical concerns relative to the heart arrhythmia, you should find an appropriate medical monitoring solution in concert with the patient’s cardiologist. But if you are looking for an alternative to a medical service, read on.

Most heart rate monitors rely on a chest strap which transmits heart rate data to a wristwatch, bike computer or even smart phone worn or carried by the individual. The MyPulse Long Range Monitor is no different, but instead of the watch to read the data, it has a small Repeater device which is carried by the individual (or located within 3’ of the person wearing the chest strap). The Repeater transmits the data to a Receiver which is connected to a PC/notebook via a USB port.

The combination of Repeater/Receiver gives the wearer a practical range of throughout the house (the kind of range you would expect to see on a Wi-Fi network for instance) and up to 1000’ if the Receiver has an unobstructed view of the Repeater. The MyPulse application runs on the PC and provides a graphic display of real time heart rate data.

Bluetooth mid range/global range monitor

This is the cool part: the software can be configured to provide alerts via email or text message to multiple recipients (such as a caregiver) if a preset limit is exceeded (such as might occur if the wearer goes into A-Fib). For you more tech savvy people, if you want to run a PC mirror app on your smart phone, you can view the real time heart rate data at anytime, anywhere, and not have to worry about waiting for an alert if a limit is exceeded.

All in all, this is a remote heart rate monitor solution that provides a low cost alternative to a medical monitoring service, if you and your cardiologist determine you don’t need such a service. Check out the MyPulse by Smart Monitor, Inc. on their website and from (using our portal link).

Bluetooth models: Additional MyPulse solutions include Bluetooth models: Bluetooth mobilePlus edition monitor, $149 and Advanced home edition bluetooth mid range/global range monitor. $299.

 In-Depth Report Of ECG Monitors

Report: Comparison of Handheld, 1-Lead/Channel ECG/EKG Recorders

I’m pleased to share a great online resource for anyone considering one of the newer hand-held ECG monitors. “Comparison of handheld, 1-Lead/Channel ECG / EKG recorders” by James W. Grier, Emeritus Professor of Biological Sciences, North Dakota State University. This report is extremely detailed and extensive (and was last updated September 2016).

He tests and compares 14 units, includes multiple photos of each step of testing and multiple print outs of the results. It’s the most thorough report on the topic you will find anywhere.
