Heart Rate Variability (HRV) Extraction from ECG Signals

This repository contains MATLAB code for extracting Heart Rate Variability (HRV) from Electrocardiogram (ECG) signals. The code has been applied in research on autonomic arounsals¹ and the detection of sleep-disordered breathing².

Features

• R peak detection algorithm from raw ECG data
• Ectopic beat detection
• Extract HRV signals from raw ECG data
• Suitable for use in sleep disorder research

Requirements

• MATLAB: Version R2018b or later
• Toolboxes:
  • Signal Processing Toolbox
  • Bioinformatics Toolbox

Installation

1. Clone this repository to your local machine:

   git clone https://github.com/MADSOLSEN/hrv-extraction.git

2. Navigate to the project directory:

   cd hrv-extraction

3. Open MATLAB and run the main script test.m to process a sample ECG:

   test.m
