Some echocardiographic measurements used in pulmonary hypertension

Qualitative assessment
Enlarged right atrium and ventricle
Right ventricular hypertrophy
D shaped left ventricular cavity with flattening of the interventricular septum in systole
Diminished/absent atrial wave of pulmonary valve
Mid systolic closure or notching of pulmonary valve
Haemodynamic assessment
Tricuspid regurgitation velocity3-150
Right ventricular outflow tract flow acceleration time
Pulmonary artery systolic flow acceleration time
Right ventricular ejection time
Right ventricular index of myocardial performance
Timing of mid systolic deceleration of right ventricular ejection
Right ventricular long axis function (marker of overall right ventricular systolic function)
