Description

Hey, I want to validate an algorithm on HR calculation using ECG signals from MIMIC III waveform and compare them to the HR related to those signals.
i know that MIMIC III waveform DB has also vital signs with a sample rate of 1/min, but i cant reach them.

1. what am I doing wrong?
2. how can I reach the vital signs of each waveform using the WFDB-python library?
3. maybe I am wrong, and MIMIC III waveform DB has no vital signs information?
