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):
60 ppm V-V Interval Timing Cycles: Single Chamber (VVI) Timing Intervals Interval (ms) = 60,000 / rate (bpm) 60,000 / 60 bpm = 1000 ms Lower rate limit (LRL): The maximum time allowed between one paced or sensed beat and the next. Sensing is critical to timing cycles.
