hrf = \frac{HR}{60}

Component: LVTiming

beattime = realtime - (⌊ \frac{realtime}{hrf} ⌋ hrf) - PRint

Component: LVElastanceFunction

Ts = TsK \sqrt{1 hrf} E_LV = \{\begin{matrix} Edia + \frac{(Esys - Edia) (1 - (\cos (\frac{π time}{Ts})))}{2} if time \geq 0 \land time ≦ Ts \\ Edia + \frac{(Esys - Edia) (1 + \cos (\frac{2 π (time - Ts)}{Ts}))}{2} if time < 1.5 Ts \land time \geq Ts \\ Edia otherwise \end{matrix}

Component: dummy

\frac{d}{d time} (dummy) = dummy (- 3)
