  • Title: [The evaluation of systolic right ventricular pressure and right ventricular hypertrophy using body surface mapping (isointegral map, isochrone map)].
    Author: Haraoka S, Yamanari H, Matsubara K, Saito D.
    Journal: Nihon Rinsho; 1995 Jan; 53(1):209-13. PubMed ID: 7897845.
    Abstract:
    We studied QRS and QRST isointegral maps, and isochrone map for the diagnosis of right ventricular hypertrophy and its severity in atrial septal defects and primary pulmonary hypertensions. The discriminant analysis in QRS isointegral map showed better results for differential diagnosis between atrial septal defects and both normal subjects and incomplete right bundle branch block patients than these in QRST isointegral map and isochrone map. Three parameters (Qp/Qs, systolic right ventricular pressure, right ventricular ejection fraction) for right ventricular overload showed significant correlation with QRS isointegral map and QRS isopotential map. Thus body surface map was an useful method for the evaluation of right ventricular hypertrophy.
