Am I able to see a smooth QRS complex with the Truesense device?
I have 2nd (sometimes 3rd degree) AV-Block (during the night mostly/ in rest) for which I have regular visits to the hospital. Somewhere in the future I need to opt for pacemaker, but not necessary at this moment.
So basically I’m looking for a device that can record (8+ hours) ecg with the ability to see clear qrs complex afterwards
Yes, TrueSense Exploration Kit can pickup full QRS waveform when worn on chest bone vertically.
You may want to get Accessory Pack and use the Comforpore film for attaching electrodes securely for long duration ECG recording using Memory Module (MM).
you can use OPI Console to convert recorded TrueSense data to _HR.txt file using View Converter function. then you can import the .txt file into Kubios program for graphical analysis, which will easily show outlier data points, and you can check against raw data to see if it’s due to muscle activity, poor contact, HR extraction bug, or REAL missed beat.
Still looking into this… Actually I’m measuring my 24/7 HR and HRV via Fluxtream Capture with a Polar H7. In addition to that I’m looking to get rid of the chest strap using soft gel electrodes so it doesn’t interfere with my breathing and to get a more comfortable fit.
But what I see is that there’s no way to get health, stress or any kind of medical utility from all this information in a way that, for example, the Firstbeat Bodyguard 2 that @Marco_Altini recommended does.
However it happens that Bodyguard 2 is not exactly of my liking because of it being an offline gadget, that’s not connected to the smartphone and this way I cannot see live information and I depend on having access to a PC instead of streaming or uploading it directly.
So what I’m looking like is a way to get 24/7 HR and HRV information, via smartphone, with some health insights like, for example Polar Loop app or any of that kind does, and the ability to export all that information for more deeper research purposes.
So far, what I that majority of the products out in the market always fullfill everything except of one of this.
Optical HRM wristbands like Fitbit and others are accurate for only HR but fail at excercising and HRV logging.
Cheststraps, while being accurate, suffer from the imposibility to store data before syncing and are affected by possible connections lost, phone battery and depends on an app. I thought it could be addressed using an wristband that stores the info before syncing but they’re not meant to be logging 24hours straight. However, in a way or another, using Fluxstream capture I had been able to store some of the information but lack of the software to analise it.
Other, and more scientifical products address some of the above problems but suffer from the imposibility to see all this information online or in my mobile, they’re stuck with old software and is difficult to move from one platform to another.
What I’m trying to get is any sort Fitbit Charge HR system, with the possibility to get the information to an open platform and with the accuracy of a chest strap.
What do you guys think about all this, what have you discovered with all the experience, what else can you add to this matter? I want to hear you!
I’m trying out Fluxtream Capture + a Polar H7 just now. It’s a little uncomfortable - I don’t think I’d like to wear it permanently, but I’m going to give it a shot for a few days. The data at Fluxtream looks good. I’m interested in comparing it with my Apple Watch to see if they agree with each other.
@ejain - I guess I’ll give up on 24 hr monitoring. I wouldnt mind something that can “track for few hours” once activated to do so (when starting the day… esp, just waking up to working out to yoga to meditation to break fast to finally getting done with daily morning routine)
Since the accuracies are not all that great, yet and I have an iPhone, which “inexpensive” HR/ BP sensor / band etc would you recommend? I just want a low cost one to play with for starters - To even see if I use it enough to maybe go for a better thing
