Primary LanguageJupyter NotebookMIT LicenseMIT

ECG plot

example 12 lead plot

Plot standard ECG chart from data.

  • Support both direct plotting and plotting SVG preview in browser (currently only works on mac)
  • Support saving PNG and SVG to disk
  • Support customer defined lead order
  • Support customer defined column count

Install

pip install ecg_plot

Notice

  • Input data should be m x n matrix, which m is lead count of ECG and n is length of single lead signal.
  • Default sample rate is 500 Hz.

Example

Plot 12 lead ECG

params:

parameter description
ecg m x n ECG signal data, which m is number of leads and n is length of signal.
sample_rate Sample rate of the signal.
title Title which will be shown on top off chart
lead_index Lead name array in the same order of ecg, will be shown on left of signal plot, defaults to ['I', 'II', 'III', 'aVR', 'aVL', 'aVF', 'V1', 'V2', 'V3', 'V4', 'V5', 'V6']
lead_order Lead display order
columns display columns, defaults to 2
style display style, defaults to None, can be 'bw' which means black white
row_height how many grid should a lead signal have
show_lead_name show lead name
show_grid show grid
show_separate_line show separate line 
import ecg_plot

ecg = load_data() # load data should be implemented by yourself 
ecg_plot.plot(ecg, sample_rate = 500, title = 'ECG 12')
ecg_plot.show()

Plot single lead ECG

import ecg_plot

ecg = load_data() # load data should be implemented by yourself 
ecg_plot.plot_1(ecg[1], sample_rate=500, title = 'ECG')
ecg_plot.show()

Save result as png

import ecg_plot

ecg = load_data() # load data should be implemented by yourself 
ecg_plot.plot_12(ecg, sample_rate = 500, title = 'ECG 12')
ecg_plot.save_as_png('example_ecg','tmp/')
