Pressure half time is the time required for the peak pressure gradient to reduce by half (1/2) which will correspond to a decrease in peak velocity by a factor of square root of two (21/2). Pressure half time of a regurgitant jet depends on the severity of the regurgitation and the compliance of the receiving chamber.
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.
