The deceleration time is another simple means of evaluating the MV area, in which decay of the mitral inflow profile through a stenotic MV is examined. The following formula describes the relationship of the deceleration time to the MV area (19):
Mean FHR rounded to increments of 5 bpm in a 10-minute window, excluding accelerations, decelerations and periods of marked variability There must be at least 2 minutes of identifiable baseline in any 10-minute window (not necessarily contiguous), or the baseline for that period is indeterminate.
