| Popis: | Adverse outcomes in heart failure occur more frequently with QRS prolongation. The results of our study have shown that 1/4 of community hospital patients with heart failure of sufficient severity leading to hospitalization have a QRS duration ofor =120 ms and that this degree of QRS prolongation is associated with substantially more severe left ventricular (LV) systolic dysfunction, LV dilation, and mitral regurgitation. |
