rsleep (version 1.0.4)

detect_rpeaks: Detects R peaks in raw ECG signal.

Description

Implements the first part of the Pan & Tompkins algorithms to detect R peaks from a raw ECG signal. Inspiration from https://zenodo.org/record/826614.

Usage

detect_rpeaks(
  signal,
  sRate,
  lowcut = 0,
  highcut = 15,
  filter_order = 1,
  integration_window = 15,
  refractory = 200
)

Value

A vector of each detected R peaks in seconds from the start.

Arguments

signal

Numerical vector of ECG signal.

sRate

ECG signal sample rate.

lowcut

Butterworth bandpass filter low cut value.

highcut

Butterworth bandpass filter high cut value.

filter_order

Butterworth bandpass filter order value.

integration_window

Convolution window size.

refractory

Minimal space between peaks in milliseconds.
