mne.preprocessing.ica_find_ecg_events(raw, ecg_source, event_id=999, tstart=0.0, l_freq=5, h_freq=35, qrs_threshold='auto', verbose=None)[source]#

Find ECG peaks from one selected ICA source.

Parameters:

rawinstance of Raw: Raw object to draw sources from.
ecg_sourcendarray: ICA source resembling ECG to find peaks from.
event_idint: The index to assign to found events.
tstartfloat: Start detection after tstart seconds. Useful when beginning of run is noisy.
l_freqfloat: Low pass frequency.
h_freqfloat: High pass frequency.
qrs_thresholdfloat | str: Between 0 and 1. qrs detection threshold. Can also be “auto” to automatically choose the threshold that generates a reasonable number of heartbeats (40-160 beats / min).
verbosebool | str | int | None: Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

ecg_eventsarray: Events.
ch_ECGstr: Name of channel used.
average_pulsefloat.: Estimated average pulse.
