5 out of 5 stars
Loved it so much I purchased one for my brother
Loved it so much I purchased one for my brother The machine is very easy to operate and learn. You get lots of instructions with it as well as during the set up. You can get help on your phone as your doing it as well as a tutorial. The reports can be saved PDF and emailed without a subscription. The charts print out clear and you get 4 pages in total. They have a lot of Utube and educational tutorials on line to help you read your own charts. The machine comes up and tells you if your reading was normal or needs your attention so really I don't find the need to read it myself. Its very small and compact so you will want to purchase a holder as well. I purchased the one shown and it fits well and delivery was fast. My brother had a stroke and he took his machine to his doctor and the doctor loved it so much he is buying one.

    4.0 out of 5 stars Surprisingly impressed so far
    Reviewed in Canada on May 19, 2024
    Verified Purchase
    I am a practicing Paramedic and also teach BLS, ACLS, PALS and ECG interpretation regularly. I bought this to see how it stacks up against conventional monitors, the Zoll M Series and The Physiocontol Lifepak 10. So far I have to say that I am impressed. I wasn't expecting much, and even considered it a waste of money, but I wanted to see if it had a place in my classes or everyday use. To start, it is no different than running a 3 lead or limb lead off the other machines. That obviously makes it a non-diagnostic ECG. That said, it prints on the standard graph paper and you can read the tracing as per other 3-leads to consider investigation. You can calculate rate and regularity and determine the presence of ectopics. It is stored in your history on your device and can be downloaded and emailed, without the subscription. The advantage it has is that it is very easy to use and quick to run. As soon as I take it out, everyone wants to try it. In my career I found numerous arrythmias that were previously undiagnosed, and this may increase the possibility of further investigation on someone who just tries out. That said it's value is equivalent to a 3-lead tracing. I have only had it for a week so far and have found it comparable to the Zoll and Lifepak. It may also find a place where people may feel reluctant to run an ECG, this would be a good starting point. I am going to start challenging it against concurrent 3 and 12-lead tracings to see it's accuracy and will add that later. My only concern is that I am afraid I might lose it. I purchased a case, but I have to find something that will keep it more secure and less likely to forget somewhere.

    All this pertains to uses not advertised. I am not sure I would buy this for the purpose of exploring whether or not I have undiagnosed A-fib. In other words, I see lots of applications for practitioners or in places where carrying a full-sized monitor defibrillator is not practical, that want to do a quick tracing versus someone wondering if they have something.

    5.0 out of 5 stars Best EKG I've Owned, But Has Drawbacks
    Reviewed in Canada on October 31, 2022
    Verified Purchase
    I've owned a few low cost home EKG devices, and this is by far the best, but there are some drawbacks...

    Pros:
    - Device and app are easy to use to take an EKG.
    - Creates a nice 6-lead reading that can be saved in a PDF and sent to doctors (several have said this is useful and helps).

    Cons:
    - Requires a paid subscription if you want it to tell you about more than the most basic results (it will ignore and not tell you certain things unless you pay).
    - Requires a phone/app to use it.
    - Not marked for orientation which can be a problem if you don't use it often and remember (have to remember their company logo and which way is up, which isn't obvious).
    - To avoid the paid subscription, you have to go through extra steps to save the results/PDF of each reading.
    - The paid subscription is a money grab which forces you to buy services you may not need so you can also unlock the full result reporting in the app, which other devices provide as part of the purchase cost.
    - Very often doesn't sense/read well so skin almost always has to be moistened in some way (never had this problem with other competing devices).

    This takes an EKG by holding the device with two hands (thumb/finger holding each side of it) and placing the back of it on your leg just above the knee, and holding for 30 secs. The app is easy to start and indicates if it is reading and the progress. Then shows the results, allows you to add notes, and you can also save/export it as a PDF.

    The results are very useful and good, though I found we often have to dampen the skin to get good contact and a good reading. The device is small enough to carry with you, and you can also use your ankle instead of your leg/knee for a 6 lead reading, or just your hands for a simpler 2 lead reading (like the lower cost model of this device).

    I definitely recommend it, and it is great for catching those events that only occasionally happen, so you can them send/show them to the doc. It's also useful for things like eliminating false worry, or recording things and adding notes, for them to be reviewed by your doctor. I don't like they way they limit the app function (reporting certain detected conditions) unless you pay a monthly subscription fee to keep in unlocked, but it will report the most basic ones, and if you just send/show this to your doc for review, the subscription isn't really needed.

    Reviewed in Spain on June 7, 2025

    Es fácil de configurar y usar. Algo molesta la propaganda en el software. Hay que ir directamente a 'HISTORIA', en la zona inferior, y allí puedes hacer ECG's y ver los ya realizados. También puedes convertirlos en PDF y descargarlos, aunque en mi caso, en el móvil se ven muy bien, pero en el PC el Adobe Reader se congela al abrirlos. Sólo puedo abrirlos con los navegadores web. Recomiendo el de seis derivaciones (6L). Los gráficos obtenidos se parecen mucho a los hechos con un electrocardiógrafo médico profesional (que suele hacer 12 derivaciones). Incluso el semento ST (repolarización) se puede distiguir bastante bien, aunque lo suyo es descartar alteraciones en la frecuencia (fibrilación auricular, bradicardias, taquicardias, arritmias, etc.), más que diagnosticar o descartar episodios isquémicos. Me pareció caro al comprarlo, pero al ver los resultados creo que vale la pena.

    Kardia mobile 6-lead device is better than the single-lead version as it gives a clearer picture of the ECG trace for heart arrythmias.

    However, the associated Kardia app is not downloadable in Singapore to Android users and the device is useless without the App. The solution is to "sideload" the Kardia app via APK from a number of sites, eg. APKPure. After installing the app, everything works perfectly.

    5.0 out of 5 stars Confirmed accurate, very simple and portable
    Reviewed in the United States on June 7, 2021
    Verified Purchase
    I bought this to have this diagnostic capability at home and in the field. I bought the Kardia unit specifically because it was the only FDA cleared device I found and because I read multiple reviews from cardiologists who liked it. It is easy to use and so far has seemed accurate.

    I like the capability of doing 6-lead readings, and the potential for field adaptability is huge. However there are a few caveats... One, you must be in a comfortable and relaxed position for an accurate reading. If you are having to actively hold the unit in place or are pressing down on the pads, it will pick up a lot of muscle artifacts just like any other EKG would. Two, if you have mobility, joint, or other range of motion problems it can be difficult to get in a position that allows you to be comfortable and relaxed while simultaneously reaching both fingertip pads and your ankle.

    I did a few test runs with this unit and shared them with a paramedic and critical care nurse. Both said the quality looked good and agreed with the device's assessment (normal rhythm). I then took it to my next doctor's appointment. The EKG tech looked at it and thought it was pretty cool and seemed to be accurate. Finally I ran this unit at the exact same time the tech ran a full 12-lead on me so I could compare, and the output was a match. So I would say this device is very accurate.

    I was leery of the app and how much access to the data I would have based on some previous reviews, however I found that it does almost everything that I need without an expensive prescription. I can record my tests and keep a log, export (email / print) the ekg graphs, and the note feature is nice.
    There are some analyses it does not perform without the subscription, which I find kind of silly - its already in the software and just not enabled, and if something like that is going on with my heart I definitely want to know and not have it withheld. I'm sure its great for some people but I don't need the quarterly cardiologist review, and I don't want my app dumbed-down just because I won't buy a subscription that I don't need. Perhaps Kardia would consider a one-time upgrade to enable the additional rhythms without subscribing to the doctor review.
    The biggest issue I have is their app constatly berates you to upgrade and buy the subscription service. Its almost difficult to use the app because the in-app advertisements and misleading pages that keep pushing the service on you even after you've told it "no". I really wish they would fix that. Its very frustrating and I almost returned the unit because of this, vut ultimately decided to keep it.

    I live and work in a remote area, and really bought this device to give me more diagnostic capability in the field. After talking with a few seasoned paramedics including some who do maintenance and repair on professional fire/ems EKG units, I will likely be modifying my Kardia unit to accept standard snap-on EKG leads. I plan to solder button snaps onto each pad, which will allow the limb leads to be placed much more easily and on patients who can't get into the necessary position for whatever reason. More importantly, the third lead can be moved around and although it is one slice at a time I can get a more complete picture of the heart when nothing else is available. I will do a lot of testing afterwards to see if there is any impact to the quality, and yes I know it's not FDA certified for this modificiation etc. but the possibility here is amazing.
    Kardia if you're reading this: A version of this device that accepts actual wire leads and ideally has more total leads, and which is aimed at professional responders such as myself would be a game changer. For rural areas where volunteers are used extensively this could make a huge difference. I rarely have the fire truck there when I get on scene, and often we're way back in the woods where lugging the equipment over rough terrain is difficult. Most of my gear is self-purchased and I don't have a $20k Physio-control LifePak with me. But I would gladly buy a $200 or $300 portable unit like this out of pocket if it had these features. I would spend another $50 even on this unit if it just had detachable wire leads.
