API¶

The API pages document Python signatures and link to executable examples. For expected inputs and outputs, scientific interpretation, limitations, and references, use the Biosiglib method catalog.

ECG¶

Function	Description
`baselineremove`	Estimate and remove baseline wander from fiducial isoelectric samples.
`pantompkins`	Detect ECG R waves and expose the processing signals.
`sloperange`	Derive a respiration signal from ECG slopes.

HRV¶

Function	Description
`fdmetrics`	Calculate frequency-domain variability metrics.
`fillgaps`	Reconstruct missing events in an ordered series.
`ipfm`	Reconstruct instantaneous heart rate and optional TVIPFM modulation.
`osp`	Separate respiration-related HRV modulation from its orthogonal residual.
`removefp`	Remove false-positive events from an ordered series.
`tdmetrics`	Calculate time-domain variability metrics.

Tools¶

Function	Description
`lpd_filter`	Apply the low-pass differentiator used by detection algorithms.
`medfilt_threshold`	Compute a median-filtered adaptive threshold.
`nan_filter`	Filter data while preserving NaN gaps.
`nan_filtfilt`	Apply zero-phase filtering while preserving NaN gaps.
`snap_to_peak`	Refine event positions by snapping them to nearby peaks.
