mne.preprocessing.find_ecg_events¶

mne.preprocessing.find_ecg_events(raw, event_id=999, ch_name=None, tstart=0.0, l_freq=5, h_freq=35, qrs_threshold=’auto’, filter_length=‘10s’, return_ecg=False, verbose=None)[source]¶

Find ECG peaks.

Parameters:

raw : instance of Raw The raw data event_id : int The index to assign to found events ch_name : None | str The name of the channel to use for ECG peak detection. If None (default), a synthetic ECG channel is created from cross channel average. Synthetic channel can only be created from ‘meg’ channels. tstart : float Start detection after tstart seconds. Useful when beginning of run is noisy. l_freq : float Low pass frequency. h_freq : float High pass frequency. qrs_threshold : float | 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). filter_length : str | int | None Number of taps to use for filtering. return_ecg : bool Return ecg channel if synthesized. Defaults to False. If True and and ecg exists this will yield None. verbose : bool, str, int, or None If not None, override default verbose level (see mne.verbose() and Logging documentation for more).

Returns:

ecg_events : array Events. ch_ecg : string Name of channel used. average_pulse : float Estimated average pulse.
