It sounds like you want HRV examples from healthy subjects. Unfortunately, I think the only datasets with posted HRV results are "special" in one way or another. SHHS has subjects with cardiovascular risk factors, CHAT has children with OSA, MESA has adults with atherosclerosis, etc.
There are certainly a wide range of subjects in each dataset, so you could look for the subjects with the lowest AHI values, lowest number of risk factors, etc. In other words, create some sort of "healthiness" index for a given dataset based on a pre-determined set of factors/variables.
I'm not 100% sure what you're asking for. Could you provide more information?
Some of our datasets have "processed" HRV data already available. See these links for examples:
Happy New Year - thanks for using NSRR!
Thanks for adding that to the discussion! I will make a note on the introduction page. Unfortunately, the original raw data and scoring for those 4 studies were lost due to a server crash many years ago.
Can you post the URL of the instructions you were following? Thanks!
Thanks for inquiring and for your interest in NSRR/dbGaP data. I am going to ping a couple others on the NSRR team who are more familiar with dbGaP and ask them to comment if they have additional information.
Here's my best attempt at answering your questions:
Good luck, please let us know if we can assist further!
Stephanie Marvin reviewed these files/issues and did what she could to fix them. In short, we removed the XML annotation files for aa2180 and replaced the files for aa2618 and aa2931.
I made some notes on the MrOS polysomnography introduction page.
A subset of our MrOS data were very problematic to export for NSRR years ago due to some past file corruption. We cleaned up as much as we could but some strange stuff still slipped through.
Thanks again for bringing these issues to our attention!
Thanks for the heads-up - we will check these MrOS files out.
Most datasets contain a "Montage and Sampling Rate Information" page, which describes the signals most commonly found in the PSG/EDF data.
Thanks for your interest in the site!
Thanks for checking out the site and data, Richard.
Yes, the XML files as-is will not work in Polyman. The "NSRR" versions of the XML annotations are designed to work with EDF Viewer. The "Profusion" XML are straight from Compumedics Profusion where the sleep studies were originally scored.
To make these "openable" in Polyman you will have to write some sort of script that translates the existing XML into the format readable by Polyman. You can explore the XML structure by opening one of the files in a text editor.
That's correct. There are individual "time until X" variables like MI, CABG, PTCA, etc. I think the CVD death variable is a composite that the dataset owners created from the other "time until fatal X event" variables, so you could probably create your own "time until first instance of CVD" from some of the other CVD Outcomes variables.
