maxPt and minPt are the maximum and minimum values respectively of the transient component of the pressure gradient in a length of 270 mm (from the mitral valve, see Figure 2). +TPt and -TPt are the duration of the positive and negative two phases of the transient component of pressure (see Figure 4).
