Sample Arrhythmia Data from MIT Boston's Beth Israel Hospital (BIH) Database

Sample arrhythmia data from the MIT-BIH Arrhythmia Database

data(arrhythmia)

Format

An object of class data.table (inherits from data.frame) with 10000 rows and 2 columns.

Details

The data includes two columns "MLII" and "V1". According to https://www.physionet.org/files/mitdb/1.0.0/mitdbdir/intro.htm, "In most records, the upper signal is a modified limb lead II (MLII), obtained by placing the electrodes on the chest. The lower signal is usually a modified lead V1 (occasionally V2 or V5, and in one instance V4)."

The data was downloaded after installing the "wfdb" Python package. The Python code used to save the sample data is the following:

import wfdb
import pandas as pd

sample_annotat_200 = wfdb.rdrecord('200', sampfrom = 0, sampto = 10000, pn_dir = 'mitdb')
arrhythmia = pd.DataFrame(sample_annotat_200.p_signal, columns = sample_annotat_200.sig_name)
