"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

"Your book [Beat Your A-Fib] is the quintessential most important guide not only for the individual experiencing atrial fibrillation and his family, but also for primary physicians, and cardiologists."

Jane-Alexandra Krehbiel, nurse, blogger and author "Rational Preparedness: A Primer to Preparedness"


"Steve Ryan's summaries of the Boston A-Fib Symposium are terrific. Steve has the ability to synthesize and communicate accurately in clear and simple terms the essence of complex subjects. This is an exceptional skill and a great service to patients with atrial fibrillation."

Dr. Jeremy Ruskin of Mass. General Hospital and Harvard Medical School

"I love your [A-fib.com] website, Patti and Steve! An excellent resource for anybody seeking credible science on atrial fibrillation plus compelling real-life stories from others living with A-Fib. Congratulations…"

Carolyn Thomas, blogger and heart attack survivor; MyHeartSisters.org

"Steve, your website was so helpful. Thank you! After two ablations I am now A-fib free. You are a great help to a lot of people, keep up the good work."

Terry Traver, former A-Fib patient

"If you want to do some research on AF go to A-Fib.com by Steve Ryan, this site was a big help to me, and helped me be free of AF."

Roy Salmon Patient, A-Fib Free; pacemakerclub.com, Sept. 2013

Consumer Handheld ECG Monitors

by Steve S. Ryan, PhD, April 2015

This category of consumer monitors has been growing of late. Going beyond just monitoring your heart rate and plus, these units capture data and display it as an ECG (EKG) in real time.

AliveCor AC-009-UA-A Heart Monitor by AliveCorAliveCor with logo

Detects A-Fib. Attaches to the back of your iPhone; ECG is obtained by holding the iPhone and placing at least 1 finger from each hand on the electrodes embedded into the back of the phone case.

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.

Newest model is 3rd generation (Doctor prescription no longer required).”

The HeartCheck™ PEN handheld ECG device is the only device of its kind 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.)

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 LivingWithAtrialFibrillation.com (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 even a $20 off discount code if you order from the manufacturer’s website. There’s also a video at:  http://www.theheartcheck.com/products/

Keep in mind that the HeartCheck™ PEN reports aren’t meant to be used for diagnosis in an emergency. Reviews on Amazon.com are mixed, but it may work for you. Read one or both of the reviews mentioned above.

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

Facelake Hand-Held ECG 80A (Helps support A-Fib.com)

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.

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 Facelake.com. The CMS-80A (ECG-80A) can be purchased directly from Facelake.com and (using our portal link) from Amazon.com.

 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  http://www.ndsu.edu/pubweb/~grier/Comparison-handheld-ECG-EKG.html

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 A-Fib.com 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.)
