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.
