What does a low dP/dt_min indicate about LV relaxation?

Explanation:
dP/dt_min shows how quickly the left ventricle pressure falls as it relaxes during isovolumetric relaxation. A steeper, more negative slope means faster relaxation, while a lower value means the pressure declines more slowly. So a low dP/dt_min indicates a slower rate of pressure decline during isovolumetric relaxation, reflecting impaired or lusitropic dysfunction of LV relaxation. This is a diastolic property, not about how strongly the ventricle contracts (systolic function) or about afterload.
