The prognostic value of QRS duration in heart failure patients with reduced ejection fraction
Objective To observe the influence of QRS duration on the prognosis of heart failure patients with reduced left ventricular ejection fraction. Methods A retrospective analysis of inhospital patients with heart failure and reduced ( less than or equal to 40%) or normal left ventricular ejection fract...

| Zusammenfassung: | Objective To observe the influence of QRS duration on the prognosis of heart failure patients with reduced left ventricular ejection fraction. Methods A retrospective analysis of inhospital patients with heart failure and reduced ( less than or equal to 40%) or normal left ventricular ejection fraction was done to analyze the QRS wave duration. Results The 3002 patients included in the study included 1745 cases with normal QRS wave duration ( |
