I want to know can mobile phones apps which use PPG be used for HRV measurements. I want to use it for my research study comprising of more 150 participants.
You are looking for very basics of HRV analysis, you can use, but i think, it is paid. Another option is Kubios, its open source for students. Another is, if you know basics of Matlab, try that one for more in-depth analysis. Go for windows software than phone apps for fast analysis.
Thankyou so much sir. I have downloaded the Kubios Hrv standard . Can I use it for my research study (n=100). Are there devices other than chest strap which I can use for collecting data.
Pragati Anil Karwande Yes you can. Many type of devices are available for ECG from 2 - 12 electrode. Even you can design your own devices for this using some amplifier and other circuits.
Sorry for a late answer - sure, you can use Welltory for your research, we have a special academy license - it's free for up to 50 participants, please, contact our support team on a chat and tell us about your research.
