An integrated system for simultaneous acquisition and processing of physiologic and ultrasound data

An integrated system has been developed to acquire and analyze simultaneous physiologic and ultrasound data. Physiologic signals can be monitored in real time on a video strip chart display to allow accurate placement of pressure catheters. Simultaneous echocardiographic images and Doppler spectra synchronized with pressure data, are stored to optical disk. Doppler and hemodynamic data can be manipulated in a graphical environment, making this a highly flexible system for the implementation of sophisticated analytical algorithms. Synchronization of these data sets allows fundamental physical aspects of intracardiac blood flow to be defined and permits a more complete exploration of cardiac physiology than the analysis of either pressure or velocity data alone.<
