A library for extracting a wide range of features from single-lead ECG waveforms. These feature are grouped into three main categories: (1) Template Features, (2) RR Interval Features, and (3) Full Waveform Features. This repository contains the feature extraction code we used for our submission to the 2017 Physionet Challenge.

In the 2017 Physionet Challenge, competitors were asked to build a model to classify a single lead ECG waveform as either Normal Sinus Rhythm, Atrial Fibrillation, Other Rhythm, or Noisy. The dataset consisted of 12,186 ECG waveforms that were donated by AliveCor. Data were acquired by patients using one of three generations of AliveCor's single-channel ECG device. Waveforms were recorded for an average of 30 seconds with the shortest waveform being 9 seconds, and the longest waveform being 61 seconds. The figure below presents examples of each rhythm class and the AliveCor acquisition device.
