Detect Ectopic Beats in RR Interval Data

Identifies ectopic (abnormal) beats by comparing each RR interval to the local median computed over a sliding window of 5 beats. Beats with deviation exceeding the threshold are marked as ectopic.

Usage

ecgQualityCheck(rr, threshold_ms = 300)

Arguments

rr

A data.frame with columns channel, rr_ms, and time_sec, as returned by ecgRRintervals.

threshold_ms

Maximum allowed deviation from local median in milliseconds (default: 300).

Value

The input data.frame with an additional logical column is_ectopic.
