WebMay 30, 2024 · The arterial waveform reflects the change in pressure over time, or dP/dt, and thus the slope of the upstroke reflects this. Generally speaking, the steeper the slope, the quicker the rise, the greater the dP/ dt, and the stronger the contractile forces appear. What does Overdamped mean?
