Hi,
I see you submitted a data request 3 days ago that is still under review. Is your prior approved request associated with a different email address?
Please tell me what version of Ruby and the NSRR gem you have installed (run "ruby -v" and "nsrr -v" at the command prompt). I suggest using Ruby 3+ and NSRR gem 8.0.0.
Only the 500 subjects selected with high quality ECG were included in the SHHS HRV analysis. That analysis involved both automated detection of QRS complexes and manual technician review.
Thus, there aren't any subjects beyond those 500 that have HRV analysis result data posted on our resource. However, there are thousands of other subjects at each SHHS timepoint with usable ECG data (in EDF signal files) that could be used in future HRV projects.
Steph,
The SHHS HRV analysis details are here - https://www.sleepdata.org/datasets/shhs/pages/13-hrv-analysis.md
A set of 500 SHHS subjects with data at both visits and high quality ECG data were selected to serve as the basis of this analysis.
Some subjects were excluded -
SHHS1: There were 14 cases with less than 5000 NN intervals for the full night, which were excluded. SHHS2: There were 5 cases without any NN intervals (200858, 201622, 202164, 203329 and 204375 -- likely atrial fibrillation) that were excluded. In addition, two other cases with less than 50% NNs during sleep time (200139 and 201315) were excluded.

Thanks for checking out the site!
The SHHS 12-lead ECG was a separate test (done at rest, in clinic) from the ECG signal from the overnight sleep monitoring.
I'll ping someone else on the team regarding your other ECG lead questions.
Hey Yan,
We don't have any in-house visualization/scoring tools. I commonly use EDFbrowser (https://www.teuniz.net/edfbrowser/) and Polyman (https://sites.google.com/view/diegoalvarezestevez/projects/polyman) to visualize EDF signals. They each support annotations as well, though the NSRR annotations would likely need to be programmatically reformatted to match the viewer's specifications.
Yes, that's totally fine. I think your colleague has also been in touch with us by email at support@sleepdata.org
This is fixed in the latest release (v0.5.0) - thanks again for posting about the issue here!

An IRB review is preferred, but not required.
Hey,
It's easier for me to list off the datasets that do not allow commercial use.
I think all the rest allow commercial use (as of this moment).
Thanks for using the site. Data requests expire after 3 years, so yours lapsed on January 9, 2022. Go ahead and start a new data request. Feel free to use similar language to your old agreement.
