Figure 7From: Algorithmic processing of pressure waveforms to facilitate estimation of cardiac elastance Use of the shear transform, B. This example is the other situation in the process of finding MN to Figure 6, i.e. the initial guess of the global minimum for MN is correct. Here, the minimum of the shear transform from P 1 to MX falls within the range of D and hence the P 1 is taken as MN.Back to article page
