Abstract: Electrical ventricular depolarization may be represented by its vectorcardiographic QRS loop, which exists in 3D space. By recognizing that the QRS loop is often a closed trajectory on a plane (2D), it is possible to change (e.g., by rotation, projection, etc.) the single-channel QRS into a different view angle along that plane to provide a viewpoint more favorable for morphologic interpretation. Any monophasic or biphasic single-channel QRS (time series) waveform can be decomposed into the form x(?,t)=sin(?t)u(t), with t spanning [0,2?], where u(t) is an unchanging intrinsic component that is generally upright and monophasic, and where sin(?t) is a changeable component of the waveform. This way, x(?,t) may be changed by replacing a parameter of the original changeable component sin(?t) with a second parameter associated with a target view of the waveform, such as the upright monophasic sin(0.5t). Meanwhile the intrinsic component remains unchanged during this change.
