1. A method of creating a virtual lead associated with an electrocardiogram signal, comprising the steps of:
- obtaining a first electrocardiogram signal from a first lead having a first angle and a second electrocardiogram signal from a second lead having a second angle, the first lead and the second lead being associated with a subject;
transforming the first and second electrocardiogram signals into a vectorcardiogram;
moving average filtering the vectorcardiogram in polar coordinate space to reduce signal artifacts prior to transforming the vectorcardiogram into a virtual electrocardiogram signal; and
transforming the vectorcardiogram into the virtual electrocardiogram signal representing a virtual lead having a virtual lead angle.

Abstract
A method of creating a virtual lead associated with a physiological recording is provided. The method can include obtaining a first physiological signal from a first lead having a first angle and a second physiological signal from a second lead having a second angle, the first lead and the second lead being associated with a subject. The method can also include transforming the first and second physiological signals into a vector representation of the first and second physiological signals and transforming the vector representation to a virtual physiological signal representing a virtual lead having a virtual lead angle.
