Detailed info on EKG and CardiaMobile.

[goldey]

Hi everybody. Prayers for the people in the hurricane zone, I just joined ChatGPT, and have been amazed at the answers it is giving me. I asked it about EKG and CardiaMobile yesterdau and got a very detailed reply about uses, pros and cons. It is too long to post here, but if you you are interested, you can ask it the same question I did, and probably get the same answer. Just ask it something like this: >>> I don't understand how they can take an EKG in only 30 seconds. If you have AFIB or skip beats, it might not show up in that particular 30-second window that you are testing. AFIB comes and goes. and what if the skipped beats happen some other time, not during those particular 30 seconds, how will it know? this just doesn't make sense. I am talking about the CardiaMobile as well as the tests they do in the doctor's office. Thank you. <<<

That is why it is called paroxysmal AF. Kardia mobile is for home personal use when patinet feels an event. Diagnosis is usually by long term Holter monitor which watches the heart constantly for a longer period. typically seven days. Horses for courses.

If you want to monitor your heart buy the wellue 24 hour monitor my cardioligist said it gave very clear results interpreting what the heart is doing though not exactly the same as a holter it gave a good idea what's going on.Someone on here recommend it and I'm happy to endorse it's usefulness

Just an update, Wellue now have a newer version of their original device that will record an ecg for 72 hours max, rather than the previous 24 hours max.

[fairgo45 in reply to ozziebob]

That's great even better I'll be upgrading for sureThanks Bob

[ozziebob in reply to fairgo45]

Just be careful on the Wellue website if you are buying anything because there are 2 versions of the newer model, one for 24 hours, the other for 72 hours. Bob.

Yes, search Wellue on this forum. I did a review and also linked to a review by The Skeptical Cardiologist.

Hi Bob, a question for you.My friend displays all the symptoms of AF, she has rapid heart rate that comes and goes and her BP fluctuates between high and low, she says it makes her feel dreadful, just like I used to feel before I was diagnosed. Only a couple of weeks ago she fainted in a restaurant and was taken to hospital. The various heart monitors picked up odd extra beats (her words) I think maybe ectopics.

She has had a holter monitor for a week and says all it's picking up is these 'odd extra beats'.

Last time she had a racing heart I took her pulse and it was jumping about all over the place, just like paroxysmal AF. I think she should go back to her consultant, an event recorder would probably catch this.

She has convinced herself that it's side effects from Indapamide but she has been on that for years.

It worries me, what are your thoughts? I know it's only an opinion. Thanks, Karen

[BobD Volunteer in reply to Karendeena]

If you are suggesting an implantable "reveal" then that is pretty radical and not without risks. A kardia to use ONLY when such events happen may be more useful short term.

[Karendeena in reply to BobD]

Thanks Bob, I was just thinking when they finally picked mine up they gave me a recorder that I held against my chest when I felt an 'episode'

[mjames1]

Yes, an ekg is only a snapshot of your heart rate and rhythm for the time period it is taken. 30 seconds is the default with Kardia although you can increase it up to two minutes. At your doctors, it's also usually 30 seconds but can be as little as 10 seconds. If you want to track your heart rate and rhythm you would need some type of Holter device.

Kardia will record up to five minutes but the automatic analysis only "looks at and reports on" the first thirty seconds

[mjames1 in reply to baba]

Thanks for the update. It used to be two minutes, But even though Kardia only looks at the first 30 seconds, you still have the rhythm strip for the full five minutes for personal or ep review, which in my opinion is more important than Kardia's AI determination.

[baba in reply to mjames1]

I agree.

[Omniscient1]

Beware. I'm not saying it's wrong but there is already a phrase in the industry for when AI goes wrong - this is an 'Hallucination'. As an example try asking how many rs there are in strawberry. The answer may give you a laugh.

Hi Omniscent.

Mr Chatty (chatGBT) is very good but sometimes gives wrong information. It's always best to check with your medic and use Mr Chatty as a prompt.

Google Health AI - interesting reading on the first page

[Omniscient1 in reply to Paulbounce]

Agreed. Like Dr Google itself, it's great as a starting point but best (imho) to use as a starting point for the conversation with the medics.

[mhoam in reply to Paulbounce]

I agree, relying on any Generative AI such as ChatGPT for health information is at best risky, possibly even dangerous. After an MRI scan I was told I had a particular gastric conditions. I used an AI tool to provide me with possible treatments. It described three possible options in very believable language. However further checking showed that the third option was complete baloney and was actually only suitable for a totally different problem.

Whilst they use extremely sophisticated mathematics, they are really just very complex auto-complete tools that predict the next words based on their training data, They "know" nothing and really do hallucinate!

This is why I bought the rather amazing Wellue 24-hour AI ECG. I feel this was a real investment. It’s not perfect, but is reassuring, comprehensive and easy to use.

How to you get KardiaMobile to do more than 30 sec or only on a different Kardia?

a I am on my third Kardia, which I have been using for about 10 years. It only reports PVCs and probably PACs if there are 3 or more in 30 seconds. If there are fewer, it reports as NSR.

But I can see if there are 1 or 2 on the chart, and it is even easier to look at the R-R interval report. It should show about a straight horizontal line—PVCs are easy to see on that chart.

Fortunately, I used to almost always have more than 3, but for the last few months, maybe one, but most often none.

"How to you get KardiaMobile to do more than 30 sec or only on a different Kardia?"

In the App on your phone go to settings.

Priofile - settings cog at top right, then ECG settings, ECG duration.

The best device for detection in early stages of AFib, when episodes are quite rare, is Apple Watch. If AFib was found then makes sense for more reliable long period monitoring. But if you have one episode per month or even per week it will not help.
