2013, Journal of the American College of CardiologyCitation Excerpt :Paradoxical interventricular septal motion; and Adverse remodeling with increased LV dilation (10,98–103). For HF patients, dyssynchronous LV contraction is also associated with increases in cardiac mortality (10,104–106).
Heart failure and mechanical circulatory support
2012, Best Practice and Research: Clinical AnaesthesiologyCitation Excerpt :In fact, there may be an association with increased mortality, especially in patients with CAD.36,37 Silverman and others discovered that there is a prolonged QRS complex in EKG of patients with HF.38,39 ACC/AHA update on HF (2009) indicated that there is no ‘consensus definition of cardiac dyssynchrony’.
Impact of myocardial perfusion abnormality on prognosis in patients with non-ischemic dilated cardiomyopathy
2010, Journal of CardiologyCitation Excerpt :We did not perform a CMR study, but patients with focal defect might have more severe fibrosis and ventricular dyssynchrony than those with non-focal defect. In patients with heart failure, QRS duration correlates inversely with LV contractile function as indexed by the maximal rate of pressure rise [27,28]. Previous studies [29,30] showed that QRS duration might be a marker of high risk in patients with DCM.

2009, Journal of the American College of CardiologyCitation Excerpt :There are, however, no trials addressing the use of isosorbide dinitrate and hydralazine specifically in the population of patients who have persistent symptoms and intolerance to inhibitors of the renin-angiotensin system. Approximately one-third of patients with low EF and class III to IV symptoms of HF manifest a QRS duration greater than 0.12 seconds (409–411). This electrocardiographic representation of abnormal cardiac conduction has been used to identify patients with dyssynchronous ventricular contraction.
