Livenpace App?

[Cliff_G]

Has anyone used the Livenpace mobile phone App?

I noticed yesterday that my Wellue ECG device came up on a Bluetooth list of available devices on my tablet, under the name I think it gets allocated under the Livenpace Windows program , rather than the one used by the Wellue Windows program, so I searched on the Google Play store and there was a Livenpace app.

I have a trace in progress at present so won't be trialling anythng until that's done and downloaded, but from the Play Store info the app looks pretty limited - unless it does a real time output of the ECG wave?

Thanks in advance

Downloaded and won't connect. Awaiting their feedback

I use two Wellue ECG monitors. Livenpace seems to be one of the names the company uses. The list of Bluetooth devices is not useful with Wellue since it connect through the app, rather than through the Bluetooth settings. My handheld device shows up as Pulsebit.

Yes, it's the App which won't connect, though if you do a normal bluetooth pairing, a) it can see it and b) you get an instant Connection has been Refused message, so there is communication

[Ppiman in reply to Cliff_G]

Interesting. These things are sent to try us! Have you tried to delete the app then reinstall, and reset the device?

Yep, I just wonder if the Livenpace App isn't compatible with the Wellue ECG. Will contact their help.

I feel sure the at some point I tried it and it wasn't. The Wellue company seems to be a part of another Chinese professional ECG manufacturer called Viacom, and there are about three other consumer company names, all with identical products - quite odd.

Quite possibly not compatible. I only wondered and wanted to see. I can't see a phone or tablet app doing anything different, apart from the possibility of real-time viewing of the waveform over bluetooth.

Re. the multiple names, I think this is for marketing reasons and at root it's all the same company. Certainly Wellue helpline advised me to use the Livenpace Windows app when I was having trouble with the Wellue one. They are identical, except that Livenpace works properly.

And none of them is brilliant at English or even web design! Still - they are good products. I do find that both of mine get my ECGs rather badly wrong at times, but the specialist I see said that it's owing to my bundle block (LBBB), which messes up the ECG.

It as because of that (reporting VT when it isn;t!) that I tried out one called a Contec PM20, also sold as EMay 6L and thankfully that doesn;t get it wrong.

Hi Steve,

Yes, I find it not great with complex rhythms (and most of mine are 🤣). In my case I have a very small/non-existent p-wave on this single lead model (better in some leads of a 12-lead), due to my original ablation, plus a LBBB too, and both probably confuse it. I get the erroneous VT too.

A key rhythm for me at present is PVCs and it's pretty good at those, my check counts (it's an easy ectopic to spot) are within a couple of percent. I had my latest ablation 7 weeks ago and since that it showed I was getting 22,000 PVCs/day, with the highest rate during the day (1000 to 1500 /hr) and lower at night (400 - 600/hr).

My EP ok'd an increase in my Flecainide to 200 mg/day from 100, from the beginning of this week, and it's been a revelation. Sinus most of the day with a small burden of PVCs (probably 120/hr), but this week's Wellue monitoring has caught something really interesting - the daytime PVCs have plummeted, but the nightime ones have stayed at the same level of 400-600/hr. 🤔🤔 So, clearly something autonomic/vagal going on here and hopefully useful info for my EP. After my first ablation in 2002 I found the Diltiazem I also got put then on was causing ectopics, so my solution now may again be to stop it. Will have to wait for follow up in a couple more months.

The Wellue and Livenpace aren't advertised as FDA approved, but if you hunt down on their approvals web site, the FDA did approve a set of sample data which Wellue/Livenpace have used for training the AI, so sort of partially approved

You have LBBB too - welcome to the small club here on HU. The specialist I see doesn't seem to have much to say about mine, and blames my ectopic atrium for everything, despite my showing hm that many of my symptoms arise when I am in NSR but with a visibly wide QRS. I do need to talk to him again about this as talking is always at a premium and I wasn't happy with how the last telephone call went. He has even given me flecainide and assured my my cardiac MRI showed it would be safe - but a search online shows it to be contraindicated in LBBB. How confusing is that?

The Wellue device has its AI algorithm approved by the FDA, I have read and, in a sense, that is all that matters given that home ECG devices seem all equally able to create an accurate ECG trace. The errors in both our cases from Wellue (of VT, for example) are part and parcel of what LBBB does to ECGs I have been assured. LBBB messes up the trace and makes even an expert analysis difficult if not impossible.
