Abstract
An apparatus for analyzing the biomechanical behaviour of the cardiac muscle and for diagnosing pathological conditions of the heart. The apparatus measures and records the rise and fall of intra-ventricular pressure monitored by a transducer installed in a cardiac catheter or in an arterial probe. The pressure versus time recordings during both the systolic and diastolic phases are mathematically analyzed, and two parameters indicative of the biomechanical conditions of the muscle are derived. The parameters are then plotted against each other on a map in which diagnostic zones of various normal and pathological heart conditions are delineated.
