QUANTITATIVE METHOD AND APPARATUS FOR MEASURING QT INTERVALS FROM AMBULATORY ELECTROCARDIOGRAPHIC RECORDINGS

摘要

This invention is a quantitative method, and apparatus for measuring a cardiac function interval (1). Beat to beat data representative of a cardiac interval is collected over an extended period of time. A series of bins, each of which has a defined value range is defined. The collected data is organized into the bins in accordance with the value of the data, and the value range of the bin. The percentage of data in each bin may be calculated based upon the quantity of data in each bin.
