Claim 19:
20. The method of claim 19, wherein determining the degree of parallel activation of a heart undergoing pacing, via a method comprising:
calculating a vectorcadiogram, VCG, or electrocardiogram, ECG, waveforms from right ventricular pacing, RVp, and left ventricular pacing, LVp;
generating a synthetic biventricular pacing, BIVP, waveform pacing by summing the VCG of the RVp and the LVp, or by summing the ECG of the RVp and the LVp;
calculating a corresponding ECG or VCG waveform from real BIVP;
comparing the synthetic BIVP waveform and the real BIVP waveform; and
calculating time to fusion by determining the point in time in which the activation from RVp and LVp meets and the synthetic and the real BIVP curves start to deviate,
wherein a delay in time to fusion indicates that a larger amount of tissue is activated before wave fronts for electrical activation meet, thereby indicating a higher degree of parallel activation.
