Septal-to-posterior wall motion delay

Fig. 11.5 M-mode short-axis view of the echocardiographic image taken at the level of the papillary muscles. Calculation of septal-to-posterior wall motion delay (SPWMD) obtained by measuring the shortest interval between the maximal posterior displacement of the septum (a) and the posterior wall (b).

Fig. 11.8 Stepwise algorithm for management of heart failure patients who are nonresponders to CRT. AV = atrioventricular CXR = chest X-ray EKG = electrocardiogram Htx = heart transplant LV = left ventricular LVAD = left ventricular assist device MR = mitral regurgitation RV = right ventricular VV = interventricular. Cardiac ischemia is evaluated in patients with ischemic cardiomyopathy. Evidence of dyssynchrony includes septal to posterior wall motion delay > 130ms, intraventricular mechanical delay >40ms, and tissue Doppler imaging > 65 ms.
