I searched the forum for WIWE and returned zero hits.
I Recently purchased the WIWE one-lead heart monitor and am very pleased. Living in Greece, the Kardia is not supported and the WIWE claims to be a little more accurate. It includes a blood oxygen scanner, and also reports HRV.
It costs some 120EUR.
Hi saulger, not heard of this particular one and I suppose it depends a bit on why you are doing your monitoring. If it's to try to help you get diagnosed you might struggle to get a GP to take the device readings seriously as the only home device that seems to be partially acceptable for readings is the Kardia. If you are using yours for your own information and long term tracking, then it's probably fine.
Hi Callendersgal. I was diagnosed with paroxysmal AFib in 2018 and can tell when I am having an episode, without a monitor. My normal resting heart rate is in the low 50's and goes up to the 120's BMP during an attack, so it's very obvious to me when the pulse is irregular.
I wanted to share this WIWE device with our group.
"Results: The algorithm was tested on the PhysioNet MIT-BIH Atrial Fibrillation Database, Long-Term AF Database, MIT-BIH Arrhythmia Database, and MIT-BIH Normal Sinus Rhythm Database. A1 produced an average sensitivity (Se) of 97.64 % and specificity (Sp) of 93.06 %. A2 resulted Se = 96.52 % and Sp = 99.12 %. Additionally, clinical data acquisition was performed by the Sanatmetal WIWE mobile ECG system. On the latter records, Se = 100 % and Sp = 95.31 % were obtained with A1, while A2 resulted Se = 100 % and Sp = 100 %."
I haven't heard of the one you mention, but I have used an Apple Watch 4 for a couple of years since my ablation for atrial flutter. However, with increasing symptoms this past six months, I decided this week to buy a separate monitor as the Watch had only flagged up afib on two occasions. I suppose it's true to say that on neither occasion did I really need the watch to tell me that.
In the end, I bought a Wellue DuoEKG as it had such good reviews and was a decent price from Amazon. Well, it works marvellously well, producing a very accurate looking trace and, for much of Sunday, it flagged up what it calls "irregular" rhythm. It's well-designed app is very easy to use .
However, it made me think. My Apple Watch wasn't showing anything like as many issues as the monitor has been doing. It occurred to me that the Watch has been programmed only to show afib, since it has been given FDA and NICE clearance for only that, whereas the monitor will flag up any kind of "Irregular Rhythm", but not label it. The Watch does show my tachycardia, and occasionally has come up with "Inconclusive" but not very often and certainly not always matching my symptoms.
I've now decided, therefore, to order a Kardia 6L, as I am hoping that will show both "irregular" as well as label it as "afib" if it is. It arrives today, so we shall see what comes of that.
I don't think the Kardia is more accurate, as you suggest, however. I think the trace of yours and my Wellue are correct and accurate; it's just that the Kardia, like the Watch, has an "algorithm" in its software to flag up, specifically, a single arrhythmia, i.e. atrial fibrillation.
Steve
Dear Steve. We meet again. Our paths also crossed when buying a HR monitor. I additionally purchased the Pulsebit EX from Wellue.
It is a one-lead ECG with an integral screen to display the trace w/o the phone.
The readings can be 30sec, 60sec, or 5mins (with wired leads).
I have the same issue that it just reports "irregular" when there is too much variation between the "RR" waves (wave to wave), without naming the issue.If you download the trace to a complementary App, an on-screen "ruler" can be used to calculate the heart rate variations at different points of the wavelet.
The WIWE, also a 1L 60 sec ECG trace, does show a lot more information.
It has an integral pulse oxygen meter, and displays warning when the PQRST portions of the wave trace are wider or narrower than the norm. Mine are widened due to my Flecainide intake.
It can allegedly detect and names various heart irregularities:
- ECG irregularities (e.g. Ventricular conduct disorder)
- Arrhythmia: Bradycardia, tachycardia, extrasystole
- Increased stroke risk (atrial fibrillation)
- Increased risk for sudden cardiac arrest (based on ventricular heterogeneity - an indication for ventricular tachycardia/fibrillation)
-Oxygen deficiency
It also has a HRV (Heart Rate Variability) report, and warnings (with graph) when the repolarisation of the heart is abnormal.
"Repolarization is the return of the ions to their previous resting state, which corresponds with relaxation of the myocardial muscle."
I use the PulsebitEX for quick scans and the WIWE when "Ireegular" is reported by the former.
The Kardia 6L is supposed to be the gold standard and has FDA clearance, but is not available or supported in Greece.
Please let us know how you find the Krdia 6L. I hope all goes well.

Hello Saul. I didn’t realise the post was from you. I’m sorry! It’s lovely to hear from sunny Greece - my favourite country! You have started me thinking now and I’ll look into the one you’ve bought.
My main issue is that I get sudden tachycardia of about 95-105bpm rising to 128 with the mildest exertion. Often the device flags that as “irregular” and shows some ectopic beats, too. If it didn’t make me feel so tired, I could pass it off, but it often does. I’ll let you know what the Kardia shows. I didn’t know it wasn’t supported in some countries. I presume it is here since Alivecor UK sells them.
Steve
Yes, Steve, the Kardia is not sold in Greece and I would not be able to download the App unless I was in a country supported by Alivecor...I will post sample reports from the WIWE. All the best. Saul
Just saw this:

I paid just 120 EUR:
"Conclusion
Handheld 1-lead ECG devices, such as WIWE, can serve as an excellent way for people to routinely monitor their ECG for potential arrhythmias at home and determine if further follow-up with a physician is indicated. There are several features of WIWE that sets it apart from other handheld and smartphone compatible ECG devices on the market today. For starters, WIWE is rechargeable and capable of collecting the user’s SpO2 and ECG at the same time. It has the ability to estimate the state of the user’s heart muscle cells through the Ventricular repolarization Heterogeneity (VH) parameter, which may be unique to WIWE. WIWE also offers improved detection of atrial fibrillation through its evaluation of the user’s P wave on the ECG. The device is in the process of gaining FDA clearance and currently retails for €380 in Europe."

I think you found a bargain and it seems an excellent device. It’s not available from Amazon in the UK but I see is available from WIWE in Europe for €240.
It seems it can show even more that the Kardia and I suspect that also requires the monthly subscription to reveal its full potential. It’s arriving later this afternoon, so I’ll see what it brings.
Steve
Good luck with the Kardia, you will not go wrong !I will post sample reports a little later.
Cheers !
Hi again Saul
I've been using the Kardia for a while now. I had to return the first one after a week as it had used 5 batteries during those few days. I bought the little leather case for it, too, for protection, but what an expensive thing that is for such a tiny piece of "leather".
I haven't paid extra for the KardiaCare package yet but I'm thinking of doing this. That allows a somewhat more detailed labelling of arrhythmia types, I gather, but also four reports by AliveCor's own ECG experts.
I've been using the device quite regularly and mostly, I am receiving "Unclassified" reports from it, with several "NSR" and a few that report "possible atrial fibrillation". My heart seems to be acting reasonably nicely these days, with the worst symptoms I have being sudden mild tachycardia (90-128bpm), worst in the mornings; I also have plenty of ectopic beats.
I can't make much out of the Kardia ECG traces myself, but I've sent a couple to my GP and I await his comments. I attach the first few seconds of one that shows "Possible Afib" but it seems to look far too regular for afib on lead 1. Can you make anything of it?
Hi Steve. Good to hear from you again. No I didn't notice anything in your Kardia that screams out AFib. In my case, AFib is very symptomatic with pressure in the chest area and lots of bloating etc. The pulse is over 120 (normal resting 56) and irregularly irregular: a few beats close together then a gap then lesser beats close together etc. Typically, when in AFib there is no "p" wave.
I would post a questions to users of the Kardia how to read the ECG.
Let me know how you get on. Saul
