1. A device for detecting a QRS complex within an electrocardiogram, comprising:

  • a lead comprising two sensors, the lead adapted to be disposed so that it senses an electrocardiogram,a processor coupled to the lead, the processor configured to;

    (i) obtain a signal from the lead and create therefrom a discrete waveform comprising a plurality of samples;

    (ii) search for a QRS complex within the discrete waveform by performing a stopping test at a plurality of regions within the waveform and identifying a possible QRS region when the stopping test is positive, wherein at least two consecutive non-overlapping regions within the plurality of regions are separated by at least one sample and less than an expected minimum QRS duration.
