Interventricular Mechanical Asynchrony Due To Right Ventricular Pressure Overload in Pulmonary Hypertension Plays an Important Role in Impaired Left Ventricular Filling.

This article presents a study on the role played by interventricular mechanical asynchrony in the impaired left ventricular. In this study, fifty-nine patients with idiopathic hypertension were measured by using magnetic resonance imaging system. To study right ventricular (RV) and left ventricular (LV) systolic contraction time, seven patients were measured by means of measuring myocardial of the RV and LV. With the help of harmonic phase strain analysis, the time from electrocardiogram R-wave trigger to peak shortening was computed as a parameter for systolic contraction duration.
