A computer system for real-time analysis of hemodynamic data from the cardiac catheterization laboratory has been developed. The system utilizes a small digital computer and is compatible with the analog recording equipment generally used in a catheterization laboratory. Calculated results are transmitted to the laboratory by closed circuit TV and are available to the operator instantaneously during the course of the procedure. A permanent hard-copy report is prepared on a teletypewriter at the termination of the catheterization procedure. Comparisons of pressures and value gradients calculated by the computer and physician demonstrate excellent agreement. By utilizing a small computer and programs generally applicable in any cardiac catheterization laboratory, this system can be exported without costly modifications into many laboratories. Additional personnel are not required for implementation.
