WebMay 14, 2024 · Raw RA waveforms were analyzed to identify the a-wave, v-wave, and x- and y-descents using a custom MATLAB program. Single-beat methods were used to calculate end-diastolic elastance (Eed) a measure of RV stiffness. Wilcoxon signed-rank test was used test differences between rest and exercise conditions (R version 4.0.3). WebJun 5, 2024 · The RA pressure waveforms were evaluated by a cardiologist and a cardiovascular surgeon independently in a blinded fashion. We determined the relative depth of the nadirs of “X” and “Y” descents. In a patient with normal RV function, the X descent nadir is usually deeper than that of Y descent (Figure 2A).
