1. A method for locating an existence of a biventricular pace pulse for electrocardiograph (ECG), comprising:

  • transforming ECG data to a 3-dimensional VectorCardioGraph (VCG);

    calculating VCG distance features comprising spatial distance and spatial velocity;

    locating a first ventricular pulse;

    calculating VCG angle features including angles between vectors and the first ventricular pulse;

    determining the existence of the biventricular pace pulse by classifying vectors based on spatial distance, spatial velocity, VCG angle features and temporal distances of vectors to the first ventricular pulse, wherein;

    an impulse response of a low-pass filter is rejected from being classified as the biventricular pace pulse based on the spatial distances and the temporal distances of the vectors to the first ventricular pulse;

    a recharging wave is rejected from being classified as the biventricular pace pulse based on the angles between the vectors and the first ventricular pulse and temporal distances of the vectors to the first ventricular pulse; and

    the biventricular pace pulse is determined to exist if an eligible pulse vector exists after performing said rejections.
