Key result
Vectorcardiographic changes closely correlated with right ventricular pressure, indicating its usefulness for assessing the severity of pulmonary stenosis.
Why the study?
Does vectorcardiography correlate with right ventricular pressure in patients with pulmonary stenosis with intact ventricular septum?
Observational (n=17)
Does vectorcardiography correlate with right ventricular pressure in patients with pulmonary stenosis with intact ventricular septum?
Vectorcardiographic parameters such as half-area QRS angle and right/leftward QRS forces correlate closely with right ventricular pressure, offering a non-invasive indicator of hemodynamic severity in pulmonary stenosis.
May support non-invasive severity assessment in pulmonary stenosis; leaves open prospective validation before clinical adoption.
Frank lead vectorcardiograms of 17 catheterized patients of pulmonary stenosis with intact ventricular septum were reviewed in order to determine the usefulness of vectorcardiography as an indicator of the hemodynamic status. A close correlation was observed between the vectorcardiographic change and right ventricular pressure. Among the measurable parameters, the half-area QRS angle in the frontal plane, ratio of right/leftward QRS forces and maximum T angle were thought to be of great value for assessment of the severity of pulmonary stenosis.
