Fig. 5From: Comparison of the prognostic values of three calculation methods for echocardiographic relative wall thickness in acute decompensated heart failureReliability of RWTs. RWT, relative wall thickness. RWTPW = 2 × PWth/LVDd, RWTIVS + PW = (IVSth + PWth)/LVDd, and RWTIVS = 2 × IVSth/LVDd in which PWth = posterior wall thickness, IVSth = interventricular septum thickness, and LVDd = left ventricular internal dimension at end-diastoleBack to article page
