CORDAT II: a new program for data acquisition and on-line calculation of hemodynamic and regional myocardial dimension parameters.
The present paper describes a new computer program for data acquisition and on-line evaluation of hemodynamic parameters. The hardware setup is based on a standard i486 personal computer equipped with an analog to digital converter and an additional display controller. During data acquisition the multitasking program automatically detects the beginning and the end of a cardiac cycle. Immediately after the recognition of a cardiac cycle the program calculates and displays user-defined hemodynamic parameters and mean values over a given time or a given number of beats. There is a high correlation between manually determined hemodynamic parameters and the parameters determined automatically by CORDAT II.
