Previous studies demonstrate that electrocardiogram (EKG) QRS complex prolongation is indicative of left ventricular () dysfunction, a manifestation of the myocardial frequently seen in . Our study sought to determine the prognostic value of QRS duration in this patient population. We hypothesized that ...
because when the QRS is close to 120 milliseconds in patients with NYHA class III/IV symptoms or QRS close to 150 milliseconds in NYHA class I/II patients, the decision to recommend CRT implantation or undertake further risk stratification investigations is critically dependent on the EKG ...

Patients whose admission EKGs demonstrated an abnormal QRS duration ( > 90 msec) were eligible for enrollment in this study. Of the 636 patients screened, 131 demonstrated an admission QRS duration > 90 msec. There was no significant change in QRS duration from admission to discharge within the...
