maximum rate of positive change in left ventricular blood pressure maximum rate of positive change in left ventricular blood pressure to left ventricular systolic blood pressure ratio 2019-12-18T14:15:28Z CMO:0003287 LVdP/dtmax/P This is a calculated measurement in which the maximum rate of positive change in left ventricular blood pressure in a subject is divided by the left ventricular systolic blood pressure in that subject and presented as a ratio, fraction, quotient or percentage, thus normalizing it to the left ventricular systolic blood pressure.
