Abstract
A method for determining the presence of atrial fibrillation includes obtaining data from at least three orthogonal leads indicative of electrical activity of a heart over multiple heart beats, averaging the data to obtain an average heart beat, generating, from the averaged data, an average heart beat vectorcardiogram (VCG) that is a function of voltage level, comparing, over a segment of the average heart beat, the average heart beat VCG with a threshold value, and indicating whether the average heart beat VCG exceeds or does not exceed the threshold value.
