The incidence of ventricular tachycardia (VT) in preoperative evaluation for noncardiac surgery in general hospitals has not been established. The aim of this study was to determine the incidence of VT, characteristics of patients with VT, characteristics of VT, and significance of VT in patients undergoing 24-h Holter monitoring as preoperative evaluation for noncardiac surgery. In 601 patients, VT was detected in 46 patients (7.7%). In patients with VT, left ventricular ejection fraction (LVEF) was lower (62.6 ± 9.3% vs. 66.6 ± 8.9%, p = 0.003), and B-type natriuretic peptide (BNP) was higher compared with patients without VT (median, 52.5 pg/mL vs. 32.8 pg/mL, p = 0.02). The maximum number of consecutive beats of VT was more frequent in the patients with LVEF < 50% than in the patients with LVEF ≥ 50% (median, 11.5 beats vs. 3.0 beats, p = 0.01). Forty patients (87%) underwent scheduled surgery without major complications.
在综合医院进行非心脏手术的术前评估中，室性心动过速（VT）的发生率尚未确定。本研究旨在确定 VT 的发生率、VT 患者的特征、VT 的特征以及 24 小时动态心电图监测作为非心脏手术术前评估时 VT 对患者的意义。在 601 例患者中，46 例（7.7%）检测到 VT。VT 患者的左心室射血分数（LVEF）较低（62.6±9.3% vs. 66.6±8.9%，p=0.003），B 型利钠肽（BNP）高于无 VT 患者（中位数，52.5 pg/mL vs. 32.8 pg/mL，p=0.02）。LVEF<50%的患者 VT 的连续最多心跳数比 LVEF≥50%的患者更频繁（中位数，11.5 次 vs. 3.0 次，p=0.01）。40 例（87%）患者按计划接受了手术，没有出现重大并发症。
