An off-line system for in-time analysis of cardiac catheterization data and for establishment of a cardiological...

The system described may be divided in two major parts: (i) automatic analysis of cardiac catheterization data running off-line on a Siemens 305 computer; (ii) storage and retrieval of the results from these analyses and additional data from related departments (thoracic surgery, internal medicine and clinical physiology) in a cardiological database on an IBM 370/155 computer. The first part is described with special regard to (i) operation and control during the phases of data collection, pre-processing, processing and storage of results; (ii) the presentation of the results in a complete and readable form and (iii) the modular design of the software. The results of an evaluation of the computer methods versus manual methods are also presented. The second part has been described with regard to the type of data entered in the cardiological database. The structure of the database and the programs used for storage and retrieval have not been described in detail in the present publication.
