Defining end-systolic pressure for single-beat estimation of right ventricle-pulmonary artery coupling: simple… but not really

Surrogates of right ventricle (RV) end-systolic pressure (ESP) used to determine RV-pulmonary artery coupling vary across studies. ESP using point of maximal time varying elastance provides most accurate estimate of actual ESP. https://bit.ly/3xuqX3B.
