DP/DTis a signal derived from pressure, typically ventricular blood pressure, that indicates the change in pressure over time.
Measured ventricular pressure provides an indication of the contractility or relaxation of the ventricles of a heart. In this way, the derivative of pressure over time (dP/dt) provides a biphasic signal that can be used to evaluate acute directional changes of contractility. Statistical measures of dP/dt, such as the mean, maximum, minimum, time to dP/dt maximum or minimum are often extracted and analyzed.
DP/DTMaximum (peakDP/DT)is one of the oldest measures of left ventricular global contractility and is a good index of ventricular performance that is not influenced by afterload, wall motion abnormalities, or the variations in ventricular anatomy and morphology.
时间了DP/DTMaximum是评估和比较多个受试者之间收缩力的有用指数。
