Aggregates the full HRV panel – time-domain, frequency-domain (AR spectrum
with normalized units), geometric and nonlinear – together with a QTc
morphology summary into a single per-channel data.frame, from an object
produced by ecgProcess (after the neurokit2
ecg_analyze() pattern).
Arguments
- processed
A PhysioExperiment returned by
ecgProcess.
Value
A data.frame with one row per channel and columns for the time-domain
(sdnn, rmssd, pnn50, mean_hr), frequency-domain
(lf, hf, lf_hf_ratio, lf_nu, hf_nu,
total_power), geometric (HRV_triangular_index, TINN),
nonlinear (sd1, sd2, sample_entropy, alpha1,
alpha2) and morphology (qt_ms, qtc_bazett,
qrs_ms) metrics. Metrics that cannot be computed (e.g. DFA on a short
recording) are NA.
Examples
pe <- make_ecg(n_time = 40000, sr = 500)
