目的:定量分析QRS波群时间和QTc间期延长预测到急诊科(ED)就诊的急性不稳定心力衰竭(ADHF)患者预后的价值。设计:在入选BASEL(B型利钠肽评价急性呼吸困难)研究的患者中实施前瞻性队列研究。测量了173例ADHF患者的QRS波群时间和QT间期。使用Bazett公式校正QT间期。主要终点是发生在720d随访期内的全因死亡。结果:27%的患者QRS波群时间延长(≥120ms),
OBJECTIVE: To quantify the prognostic value of QRS complex time and QTc interval prolongation in patients with acute unstable heart failure (ADHF) who are referred to the ED. Design: A prospective cohort study was conducted in patients enrolled in BASEL (B-Type Natriuretic Peptide Assessment of Acute Respiratory Dysfunction) study. QRS complex time and QT interval were measured in 173 ADHF patients. Use the Bazett formula to correct the QT interval. The primary endpoint was all-cause death that occurred during the 720-day follow-up period. Results: 27% of patients with QRS wave group prolonged (≥ 120ms)
