ECG5000: ECG 5000 dataset

In moviedo5/fda.tsc: Functional Data Sets for Time Series Classification

Description

The data was pre-processed in two steps: (1) extract each heartbeat, (2) make each heartbeat equal length using interpolation. This dataset was originally used in paper "A general framework for never-ending learning from time series streams", DAMI 29(6). After that, 5,000 heartbeats were randomly selected. The patient has severe congestive heart failure and the class values were obtained by automated annotation

Usage

data(ECG5000)

Format

The variables are as follows:

• df: data.frame with the following variables:

  • class: Corresponding class level of “ECG” curves with 4 classes.

  • sample:Factor variable. In TSC database, the first 500 values (sample=train) are used for training sample and the rest of 4500 (sample=test) for testing.

• x: fdata class object with with n=5000 curves (per row) in 140 discretization points (per column).

Details

The original dataset for "ECG5000" is a 20-hour long ECG downloaded from Physionet. The name is BIDMC Congestive Heart Failure Database(chfdb) and it is record "chf07". It was originally published in "Goldberger AL, Amaral LAN, Glass L, Hausdorff JM, Ivanov PCh, Mark RG, Mietus JE, Moody GB, Peng C-K, Stanley HE. PhysioBank, PhysioToolkit, and PhysioNet: Components of a New Research Resource for Complex Physiologic Signals. Circulation 101(23)".
