Description of the issue, including:

  import wfdb
  line = 'p08/p086831/p086831-2130-12-29-18-28n'
  line_parts = line.strip().split('/')
  record = wfdb.rdrecord(line_parts[2], pn_dir=f'mimic3wdb-matched/{line_parts[0]}/{line_parts[1]}')

  The above will throw an error due to an error in the database.

Comparing this record with the original de-identified record (38/3855262/3855262n), it's apparent that the original record is correct and the matched header file is broken for some reason.

This particular problem appears to affect only the one record, although there are a handful of other records that look odd (the matched header file doesn't match the original de-identified header file as I would expect):

./p02/p021734/p021734-2136-12-06-18-17n.hea
./p02/p029712/p029712-2143-09-09-13-45n.hea
./p02/p029712/p029712-2143-09-09-13-46.hea
./p02/p029712/p029712-2143-09-11-11-45.hea
./p02/p029712/p029712-2143-09-11-11-45n.hea
./p06/p069293/p069293-2185-07-26-16-46.hea
./p06/p069293/p069293-2185-07-26-16-46n.hea
./p08/p086831/p086831-2130-12-26-13-46.hea
./p08/p086831/p086831-2130-12-26-13-46n.hea
./p08/p086831/p086831-2130-12-29-18-28n.hea

p06/p069293/p069293-2185-07-26-16-46.hea has a one-sample gap randomly inserted in the middle. The others have starting timestamps that are slightly different.

I also took a look at the waveform records, and there was 1 record out of all the records that threw an error:

got FileNotFoundError on record: p01/p017488/p017488-2153-10-19-16-24

So looks like even the waveform records have some issues.
