A Computerized System for Optimal Filtering of Left Ventricular Pressure Data

On account of noise, considerable errors appear in standard pressure-record estimates of left ventricular performance. These errors can be reduced by adequate data processing. A clinically useful criterion of such processing of left ventricular pressure is presented. The reproducibility and clinical usefulness of the method are demonstrated by application to a number of experimental records as well as to a series of simulated pressure waves.
