A multichannel data acquisition package for reduction of systemic and coronary hemodynamic data that utilizes a personal microcomputer is described. The system provides a printout of heart rate, maximal rate of left ventricular pressure development (+dP/dt), maximal rate of ventricular relaxation (-dP/dt), absolute and normalized myocardial segment lengths, the degree of shortening of the segment over the cardiac cycle, systolic, diastolic, and mean coronary blood flow velocities, left ventricular systolic and end diastolic pressures, and systolic, diastolic, and mean aortic blood pressure from six channels of input data. Obtained values are precisely linked to the cardiac cycle. To illustrate the output of this system, data obtained by reading strip-chart records are compared to microcomputer-derived values in conscious, instrumented dogs.
