Pulse graph and measurements. Note. h₁: amplitude of the peak of the main wave; h₂: amplitude of the gorge of the main wave; h₃: amplitude of the peak of the prodicrotic wave; h₄: amplitude of the dicrotic notch; h₅: amplitude of the dicrotic wave amplitude; t₁: time of the peak of the main wave; t₂: time of the gorge of the main wave; t₃: time of the peak of the prodicrotic wave; t₄: time of the dicrotic notch; t₅: time of the peak of the dicrotic wave; t: time from the starting point to the ending point of the pulse graph; : width of the upper 1/3 of the main wave.
