Abstract:
Objective To investigate the feasibility of the simultaneous measurement of right ventricular pressure-volume loops by cardiac catheterization and 2D electrocardiogram. Methods Patients referred for pulmonary hypertension underwent right heart catheterization in our hospital between June 1st, 2015 and June 1st, 2017 are to be enrolled in this study. The right ventricular volume was measured simultaneously by catheter and electrocardiogram. The pressure-volume loops were constructed by the parameters of the pressure and volume in the same cardiac cycle. Results The study completed in four cases and their pressure-volume loops were drawn. The obtained images were irregular and there was no relationship among them. As a result, the construction was a failure. Conclusions The construction of the right ventricular pressure-volume loops of pulmonary hypertension patients by simultaneous catheterization and 2D electrocardiogram is difficult to overcome the technology defects.
