## Detailed Description

    ECG heartbeat detection algorithms
    General useage instructions:
    r_peaks = detectors.the_detector(ecg_in_samples)
    The argument ecg_in_samples is a single channel ECG in volt
    at the given sample rate.

## Constructor & Destructor Documentation

## ◆ __init__()

def ecgdetectors.Detectors.__init__ | ( |  | self,
|  |  | sampling_frequency = `False`
| ) |  |

    The constructor takes the sampling rate in Hz of the ECG data.
    The constructor can be called without speciying a sampling rate to
    just access the detector_list, however, detection won't
    be possible.

## ◆ get_detector_list()

def ecgdetectors.Detectors.get_detector_list | ( |  | self | ) |

    Returns a 2D array of the different detectors in the form:
    [[description1,detector1],[description2,detector2], ...]
    where description is a string and detector a function pointer
    to the detector. Use this for benchmarking to loop through
    detectors.
