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.

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;
- and
- transforming the vectorcardiogram into a virtual electrocardiogram signal representing a virtual lead having a virtual lead angle.
A method of diagnosing and/or monitoring a cardiac condition, comprising:
- 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;
- determining a monitoring angle;
- transforming the first and second electrocardiogram signals into a vectorcardiogram;
- and
- transforming the vectorcardiogram into a virtual electrocardiogram signal representing a virtual lead having the monitoring angle.
