Description
Hi,
I have downloaded files from drivedb database (using WFDB software package, or with .dat files) and I have noticed that all the data is resampled to 15.5 Hz. However, this sampling frequency is small for ECG signal, which I'm particularly interested in. I have read the paper from the contributor, and they have collected ECG signal with 496 Hz sampling frequency. Is there any way to get the data with original sampling frequency?
Thank you in advance.

Research direction
Start by tracing how WFDB retrieves files from the drivedb database and where the reported 15.5 Hz sampling frequency is introduced. Check whether the source data and its original 496 Hz metadata are available. Done means documenting or enabling retrieval at the original sampling frequency, with the ECG data and metadata remaining consistent.
