2015, American Journal of CardiologyCitation Excerpt :This association was still significant after adjustment for clinical variables and MPI results. Previous studies have shown the prognostic significance of QRS duration in patients with cardiac disease, including heart failure,1,2 left ventricular systolic dysfunction,3 acute coronary syndrome,4 and atrial fibrillation.5 In the past years, more evidence has come into existence addressing the prognostic significance of prolonged QRS duration in a relatively lower risk group of patients, including patients referred for suspected CAD and the general population.
Association of QRS duration and survival in dogs with dilated cardiomyopathy: A retrospective study of 266 clinical cases
2011, Journal of Veterinary CardiologyCitation Excerpt :Another study demonstrated that a prolonged QRS duration was an independent predictor of increased mortality and sudden cardiac death among patients with cardiomyopathy, HF and 10 or more ventricular premature complexes (VPCs) per hour.3 Many other studies have been done and they have demonstrated a relationship between a prolonged QRS duration and a worsening of the prognosis, including an increased risk of death.3–6 The aim of this study was to determine whether there was a similar relationship between QRS duration and survival in dogs with DCM, based on a simple cut-off value on the surface ECG.
