calculated left ventricular blood pressure maximum rate of negative change in left ventricular blood pressure jsmith CMO:0001746 PMID:32207065 maximal slope of the diastolic pressure decrement VT:0010750 dP/dtmin clinical_measurement_ontology peak LV -dP/dt A calculated hemodynamic measurement related to the ability of the heart left ventricle to relax. The point at which the negative pressure fall velocity reaches its peak is taken to be the onset of isovolumic relaxation of the left ventricle. rate of maximum negative change in left ventricular blood pressure 2013-07-31T15:27:12Z
