Doctors & patients are saying about 'Beat Your A-Fib'...

"If I had [your book] 10 years ago, it would have saved me 8 years of hell.”

Roy Salmon, Patient, A-Fib Free,
Adelaide, Australia

"This book is incredibly complete and easy-to-understand for anybody. I certainly recommend it for patients who want to know more about atrial fibrillation than what they will learn from doctors...."

Pierre Jaïs, M.D. Professor of Cardiology, Haut-Lévêque Hospital, Bordeaux, France

"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."

Dr. Wilber Su,
Cavanaugh Heart Center, 
Phoenix, AZ

"...masterful. You managed to combine an encyclopedic compilation of information with the simplicity of presentation that enhances the delivery of the information to the reader. This is not an easy thing to do, but you have been very, very successful at it."

Ira David Levin, heart patient, 
Rome, Italy

"Within the pages of Beat Your A-Fib, Dr. Steve Ryan, PhD, provides a comprehensive guide for persons seeking to find a cure for their Atrial Fibrillation."

Do-It-Yourself ECG: A Review of Consumer Handheld ECG Monitors

by Steve S. Ryan, PhD, Updated April 2017

This category of consumer heart rate monitors has been growing of late. Going beyond just monitoring your heart rate and pulse, these units capture data and display it as an ECG (EKG) in real time (Note: not a replacement for an ECG performed by your doctor).

Apple Watch

To monitor for A-Fib yourself, the Apple Watch (Series 6, the gold standard of wearable monitors) can generate an ECG similar to a single-lead electrocardiogram. It’s very sophisticated and can monitor both for A-Fib and for many other health parameters. The series 6 has a blood oxygen sensor as well as a heart-rate check. Upon FDA approval, it will have real-time monitoring of blood pressure.

Added: August 6, 2020: Marilyn Shook writes “Love my Apple Watch 5! Great accurate ECG strip to share.” (Read Marilyn’s A-Fib story at

The main alternatives to the Apple Watch are the Samsung Galaxy Watch and wearables featuring Google’s Wear OS softwear. The market leader for Wear OS is Fossil (Generation 5)  Another Fossil product is the Diesel On Fadelite. The Suunto 7 from Finland has GPS.

AliveCor Kardia Heart Monitor

For a full, detailed review, see: 2016 Update: AliveCor Kardia Review by Travis Van Slooten.

Detects A-Fib. The Kardia monitor is a FDA-approved device that works with your smartphone (or tablet) and allows you to take an ECG recording of your heart from the comfort of your home, office, or anywhere.

The Kardia consists of two parts: the device itself, a small, wireless component that attaches or sits in close proximity to a cell phone or tablet, and it syncs to the second component, a smartphone app.

Three ways to hold the Alivecor Kardia to capture an ECG reading at

Three ways to hold the Kardia to capture an ECG reading.

It’s very straight forward to use the device. After you download the app to your smartphone, open and click on “Record Now”; then press your fingers to the device. As soon as you click on the green “Record Now” button, with your fingers on the device, the app displays an ECG reading of your heart in real-time and records it.

Most digital technologies for A-Fib detection record brief windows of pulse or electrocardiographic data, then use algorithms to determine a patient’s rhythm. “These algorithms have been shown to be highly accurate when compared to expert review of clinical-grade electrocardiograms (ECGs).”

Your data is accessible through the AliveECG app, also stored on secure, encrypted servers, so you can view them anywhere and share them with your doctor. Retails for under $100.

The HeartCheck™ PEN handheld ECG device from CardioComm Solutions

Heart Check Pen

The HeartCheck™ PEN handheld ECG device from CardioComm Solutions

The HeartCheck™ PEN handheld ECG device is cleared by the FDA for consumer use. No prescripton required. (There is second device that does require a prescription to order it, the HeartCheck™ ECG Handheld Monitor.)
Added: 9/6/21: Sydney MCDONNELL from CardioComm solutions writes ” We have a new handheld ECG device called the HeartCheck CardiBeat that is used with IOS and Android smart devices.”

The pocket-sized PEN allows you to take heart readings from anywhere, the moment symptoms appear. Then using the USB cable provided, connect the device to your PC and run ‘GEMS™ Home’ program to upload your heart rhythm files containing your ECGs and send it to a physician or ECG Coordinating Center (for a fee). The  ECG Coordinating Center or physician will create an ECG report on your heart analysis identifying any potential issues. The report will be made available on your PC through the GEMS™ Home program.

There’s a good review of the Heart Check pen by  over at (posted Sept. 2013). Robert goes into great detail about how to “unlock” your device to you can see the actual reading, the costs of reports (the first one is free), and the details about how all this works. There’s also a video at:

Keep in mind that the HeartCheck™ PEN reports aren’t meant to be used for diagnosis in an emergency. Reviews on are mixed, but it may work for you. Read one or both of the reviews mentioned above. Order direct at the online store or Price: $259 – $350.

Handheld ECG Monitor CMS-80A from FaceLake (or Contec)

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

Facelake Hand-Held ECG 80A

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 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.

Thermal printout from the Handheld ECG Monitor CMS-80A ECG

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.

Note: This unit does not require a prescription from your doctor. For more info and to see what the display looks like, use this link to go to The CMS-80A (ECG-80A) can be purchased directly from and other retail outlets (price $299-$380).

 In-Depth Report Of ECG Monitors

For an extensive evaluation of the above three hand-held ECG monitor with multiple photos and scans see James Grier’s Comparison of Handheld, 1-Lead/Channel ECG/EKG Recorders” at

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

I’m pleased to share a great resource for anyone considering one of the newer hand-held ECG monitors. Comparison of handheld, 1-lead/channel ECG / EKG recordersby James W. Grier, Emeritus Professor of Biological Sciences, North Dakota State University. This report is extremely detailed and extensive (and was last updated March 19, 2014).

He tests and compares eleven units, includes multiple photos of each step of testing and multiple print outs of the results. (Jim’s first report was posted in 2006 and has been updated in 2008, 2013, and in March 2014).

It’s the most thorough report on the topic you will find anywhere. (BTW: We hope to get Jim to write an article or two for about his own A-Fib. (He’s also involved with an upcoming A-Fib medical study about scuba diving that’s being developed by the dive-medical organization, Divers Alert Network, or DAN.)
