Plot Annotated ECG Waveform

Source: R/ecg-plot.R
plotEcgWave.Rd

Plots the ECG waveform with P, QRS and T fiducials from ecgDelineate. The detected R-peak sample indices are attached as the "peaks" attribute (a beat-editing hook); the delineation is attached as "delineation".

Usage

plotEcgWave(x, peaks, channel = 1, window_sec = 10, assay_name = NULL)

Arguments

x

A PhysioExperiment object with ECG data.

peaks

R-peak table from ecgDetectRpeaks.

channel

Channel to plot (default: 1).

window_sec

Seconds of signal to display from the start (default 10; NULL for the whole recording).

assay_name

Input assay name (default: first assay).

Value

A ggplot object with "peaks" and "delineation" attributes.
