Example analysis of a PPG/ECG waveform using the vital_sqi package
The following notebook shows an example of PPG/ECG waveform processing using the vital_sqi package. The aim of the package is to automate signal quality classification for PPG/ECG waveforms. It is achieved by computing various signal quality indices for each signal segment and using them to form a decision.
The pipeline can be briefly summarized as follows:
Load dataset under analysis
Preprocess and segment the dataset
Compute SQI for each dataset segment
Make decision for each segment
Global Imports
[1]:
import numpy as np
import warnings
import os
import pandas as pd
import matplotlib.pyplot as plt
import vital_sqi
from vital_sqi.data.signal_io import ECG_reader,PPG_reader
Start by importing the signal via the PPG_reader function
The function expects a .csv or similar data format with named columns. The column names are used to separate between data column, timestamp columns and any additional information columns. This returns a SignalSQI class that is compatible with other vital_sqi package functions, the main class members of interest are: * signals: an ndarray of shape (m, n) where m is the number of rows and n is the number of channels of the signal * sqis: an ndarray of shape (m, n) where m is the number of signal segments, n is the number of SQIs. * sampling_rate: sampling rate in hertz (Hz)
