Abstract
An ambulatory electrocardiographic tape recording (DCG) taken over an extended period of time, such as 24 hours, is analyzed with substantial accuracy by randomly selecting a sample of time periods of a specific duration (such as a 2% sample) and printing out a hard copy record of the electrocardiogram at these times for visual analysis. The simplicity of this method and the system performing it combined with high accuracy in quantifying cardiac arrhythmias makes it perferable for most clinical purposes to conventional methods of analyzing DCG's.
