Key result
A novel piezoresistive pressure transducer enables quantitative recording of static application pressure and variable forces associated with the heartbeat to study myocardial motion dynamics.
A novel piezoresistive pressure transducer enables quantitative recording of precordial pressure to study myocardial motion in various pathological conditions.
Not ready for clinical use; leaves open quantitative research on myocardial motion dynamics.
Novel instrumentation is described that makes quantitative recording of the precordial pressure possible. A piezoresistive pressure transducer is employed to sense both the static application pressure as well as the variable forces associated with the heart beat. The fundamental theory and some experimental data with medical interpretation is also presented. This new instrument is useful for studying the dynamics of myocardial motion and it is changed in various pathological conditions.
