1. 5/5Must have if A Fib

   I went for three years after my initial A Fib episode without a reoccurrence. At times I would wonder if this app and device really worked. Then right before I was going to be leaving town for two weeks I felt a little different and the app told me I was having A Fib. I checked it several times over the next hour and then called my cardiologist and emailed him through the app. I then met him at the emergency room and he did a cardio Version and thanks to this device and app I was able to leave town with a clear mind instead of dealing with this in a strange city. To be able to know on my own what is going on with my heart is worth way more than the price of this incredible device and app! I also have an Apple Watch because it can synch with my elliptical when I am exercising. The Kardia app and device give a more accurate EKG than the Apple Watch. There are times that I am feeling palpitations and the Apple Watch misses it but the Kardia shows it as I am feeling it. Years ago with the Apple Watch 3, Kardia had a watchband that gave EKG capability to the Apple Watch. That is the only reason why I bought the Apple Watch 3 and probably a lot of other people only bought the Apple Watch for the same reason. Then, when Apple wanted to have the technology in a new version of the watch, they screwed Kardia and went elsewhere for the technology. Years later, the technology still is not as good, which only cheats the Apple Watch customer and not any consequence to Apple for poor business ethics.

2. 5/5A True Personal Health Tool

   I was having heart palpitations and brief rapid heart rate episodes lasting any where from minutes to hours. I went through the regular cardiac tests..... stress test, blood work, EKG, echo, and 48 hour mobile heart monitoring. The palpitations and rapid heart rate did not surface during these test. How discouraging, because my symptoms were real but not solid proof. My cardiologist was concerned but not convinced there could be a problem. I mean after all doctors work with concrete facts. I remembered I had a Kardia, AliveCor Mobile EKG which I had purchased a year or so before these symptoms to help with my mother's heart tracking. I started monitoring my palpitations with the view to sharing the results with my doc. I also used the device when I started to have longer rapid heart rate episodes which were sporadic and usually occurred when the Doc's office was closed. (Who can run to the doctor at a moments notice and get in? Not me) Bingo! Proof that my symptoms were real. I printed out the EKG records I had taken with my Kardia, faxed them to my cardiologist, and received a call the same day with the diagnosis of Afib. I truly believe a correct diagnosis came about faster, without a possible emergency room visit, and in the comfort/safely at home only because of this fabulous device and easy to use app. For under a hundred dollars it's the BEST investment in my and my family's health I have made.

3. 5/5Time Out

   I have had atrial fibrillation for a number of years. During that time if I felt anything “off” I went to the ER. After relaxing and working with meditation all the symptoms went away every time. The doctors seemed to be as surprised as I was. There were many false alarms. At the hospital I was routinely checked-out. With 20 minutes of meditation all the systems were normal. My cardiologist was pleased with how I was being proactive. He showed me the Kardia app and I purchased it that day. The app gave me such peace of mind. I could use it to determine if I was having a heart event and needed to relax and check again to determine if I needed to go to the ER. Now, which is two years later, I have done routine daily readings and I’ve had no sign of a-fib except two times. I sent the results for an immediate reading and feedback. 20 minutes later—but using meditation and quietly coping whatever was going wrong had already resolved any concerns before my results even had been reported back to me. I keep my yearly check-ups and I’m doing great. Given my experience I recommend the Kardia app. It’s a great tool in your fight with heart disease. It’s peace of mind and no false alarm trips to the ER. It’s a huge piece of what I do to stay well and deal with my heart irregularities in a very wise way. Best of luck to anyone reading this post.

4. 5/5Great Tool - ICU RN gives thumbs up

   30+ years in Critical Care nursing, and w/ a few health issues of my own now, I can only say “Wow!” This is a great tool for those wishing to know if they are having Atrial Fibrillation episodes so they can get prompt treatment. Treatment of A-fib is vital in preventing strokes, death, and disability. I was able to determine my skipped beats were not PVC’s from coffee consumption but PJC’s and probable culprit taking more levothyroxine than my thyroid levels warrant (plus my old pal, caffeine). Got my thyroid levels checked and Bingo! The intrinsic interpretation function will not give you that kind of diagnosis (only gives normal or not, a-fib or not options) unless you pay for an expert interpretation ($19) or get Premium package. If you can read ECG’s already, then this can help identify PSVT vs rapid A-fib, and many other dysrhythmias. No substitute for going to your provider, but the ability to share your rhythm strip is REALLY INVALUABLE. Option to carry it on your phone is brilliant because folks always have phones on their person to capture evrnts. I have added it to my first aid kit. Home health agencies should be using these and anyone doing wellness checks on older adults. I wonder how many lives this tool has saved, and how many strokes it has prevented? Amazing! Thank you!

5. 5/5Diary Awkward, Data transfer better

   First of all, this device correctly diagnosed AFib following a heart valve replacement. It happened on Sunday. I sent the EKG to my surgeon. He concurred with the diagnosis arranged an appointment the next day with my cardiologist. I got on blood thinners and beta blocker and had a Cardioversion two days later. I’ve had one other episode since then and we adjusted my medication. This is the latest version of the app that just came out. The data transfer with my OMRON BP monitor works much better. Transfers first time, every time. I have both the 1-Lead Kardia Mobile and I just got the 6-Lead version. Easy to switch between the two or to choose 1L or 6L on my 6L device. The diary has gotten awkward. The Meds, BP, weight, are all in a big list. You must scroll through the list to find the item you are trying to mark. I’d recommend having the diary items items back in groups, EKG, weight, BP, Meds, etc. Also, there should be a way to mark Meds taken by groups- Morning, Noon, Dinner, Bedtime. Finally, with COVID-19 going around, it would be nice to have diary entry for body temperature. Also, for diabetics, an entry for Blood Glucose level, with averaging/graphing functions. That would make this app a one-stop shop.

3. 5/5

   After atrial flutter & fibrillation last year, I purchased the Kardia mobile, and it reported the problems. After I had an Ablation, I continue to check with the Kardia Mobile and it now always tells me I'm in Normal Sinus Rythym. And I can forward the Information to my cardiologist.

   Great tool. As a retired cardiac nurse, my 6 lead helps me to limit or extend my exercise programs with confidence. Most important of course is to listen to your body
