pyvital
Open source Python library for biosignal analysis. Provides signal processing utilities and medical algorithm implementations for vital signs data.
Installation
pip install pyvital
Core Functions
The pyvital package provides signal processing utilities directly at the package level:
import pyvital
# Interpolate NaN values
data = pyvital.interp_undefined(raw_data)
# QRS detection (Pan-Tompkins algorithm)
r_peaks = pyvital.detect_qrs(ecg_data, srate=500)
# Blood pressure / pleth peak detection
minlist, maxlist = pyvital.detect_peaks(abp_data, srate=100)
# Bandpass filter
filtered = pyvital.band_pass(data, srate=500, fl=5, fh=15)
# Resampling
resampled = pyvital.resample_hz(data, srate_from=500, srate_to=100)
Filters
Each filter module implements a run(inp, opt, cfg) function and a cfg dict describing its inputs, outputs, and parameters.

Filter Server
pyvital includes a built-in HTTP server (Sanic) that exposes filters as REST endpoints:
python -m pyvital [filter_folder] [port]
GET /returns the list of available filters and their configurations.POST /<module_name>runs a filter with gzip-compressed JSON input.
