Matching by time

[mvandenhi]

Dear all,

thank you very much for open-sourcing your research and mapping, which is very valuable! In MIMIC-IV-ECG it is stated that "the date and time for each ECG were recorded by the machine's internal clock, which in most cases was not synchronized with any external time source. As a result, the ECG time stamps could be significantly out of sync with the corresponding time stamps in the MIMIC-IV Clinical Database." Did you notice any problems in this regard? I.e. I am unsure how trustworthy the mapping is, as I don't know whether the clock discrepancies might be in the order of minutes or rather months/years.

Also, is there a reason, beyond the will to focus on ED, that you chose to only analyze the emergency department ECG's instead of including the hospital too?

Thank you for your contributions, Moritz
