Find ECG events by localizing the R wave peaks.
The raw data.
The index to assign to found ECG events.
The name of the channel to use for ECG peak detection.
None (default), ECG channel is used if present. If
no ECG channel is present, a synthetic ECG channel is created from
the cross-channel average. This synthetic channel can only be created from
Start ECG detection after
tstart seconds. Useful when the beginning
of the run is noisy.
Low pass frequency to apply to the ECG channel while finding events.
High pass frequency to apply to the ECG channel while finding events.
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).
Number of taps to use for filtering.
Return the ECG data. This is especially useful if no ECG channel
is present in the input data, so one will be synthesized. Defaults to
Whether to omit bad segments from the data before fitting. If
(default), annotated segments whose description begins with
False, no rejection based on annotations is performed.
New in version 0.18.
The events corresponding to the peaks of the R waves.
Name of channel used.
The estimated average pulse. If no ECG events could be found, this will be zero.
The ECG data of the synthesized ECG channel, if any. This will only
be returned if
return_ecg=True was passed.
