Scatter diagram analysis for distinguishing sinus rhythm from monomorphic ventricular tachycardia

The author has recently developed Scatter Diagram Analysis (SDA), a very computationally efficient technique for determining whether signals measured from two sites have a repeatable temporal relationship. In this paper, SDA is extended to distinguish between signals which have regular though different temporal relationships between signals measured at two sites. Two such signals are sinus rhythm and monomorphic ventricular tachycardia.
