目的 探讨心率变异性及心率震荡对煤工尘肺患者室性早搏的预测意义.方法 选择100例煤工尘肺患者伴室性早搏(偶发室性早搏44例,频发室性早搏56例)为煤工尘肺组,50例健康煤矿工人为对照组.用24h动态心电图(DCG)监测及分析室性早搏的变化,计算心率变异性(HRV)指标:时域指标(SDNN、SDANN)、频域指标(HF、LF)和心率震荡(HRT)指标:震荡初始(TO)、震荡斜率(TS),比较煤工尘肺组与对照组HRV及煤工尘肺偶发室性早搏组及频发室性早搏组与对照组HRT的变化.结果 煤工尘肺频发室性早搏夜间的发生率(66.1％,37例)高于昼间(33.9％,19例),差异有统计学意义(P＜0.05).煤工尘肺组HRV(SDNN、SDANN、HF、HL)各指标均低于对照组,差异有统计学意义(P＜0.05).对照组夜间HRV各指标高于对照组昼间,差异有统计学意义(P＜0.05);煤工尘肺组夜昼间HRV各指标比较,差异无统计学意义(P＞0.05).与对照组比较,煤工尘肺偶发室性早搏组及频发性室性早搏组TO值升高、TS值降低,差异有统计学意义(P＜0.05);与偶发室性早搏组比较,频发室性早搏组TO值升高、TS值降低,差异有统计学意义(P＜0.05).结论 煤工尘肺患者频发性室性早搏组自主神经功能受损严重,HRV、HRT异常可作为评价煤工尘肺患者频发室性早搏的预后指标.
目的 探討心率變異性及心率震盪對煤工塵肺患者室性早搏的預測意義.方法 選擇100例煤工塵肺患者伴室性早搏(偶髮室性早搏44例,頻髮室性早搏56例)為煤工塵肺組,50例健康煤礦工人為對照組.用24h動態心電圖(DCG)鑑測及分析室性早搏的變化,計算心率變異性(HRV)指標:時域指標(SDNN、SDANN)、頻域指標(HF、LF)和心率震盪(HRT)指標:震盪初始(TO)、震盪斜率(TS),比較煤工塵肺組與對照組HRV及煤工塵肺偶髮室性早搏組及頻髮室性早搏組與對照組HRT的變化.結果 煤工塵肺頻髮室性早搏夜間的髮生率(66.1％,37例)高于晝間(33.9％,19例),差異有統計學意義(P＜0.05).煤工塵肺組HRV(SDNN、SDANN、HF、HL)各指標均低于對照組,差異有統計學意義(P＜0.05).對照組夜間HRV各指標高于對照組晝間,差異有統計學意義(P＜0.05);煤工塵肺組夜晝間HRV各指標比較,差異無統計學意義(P＞0.05).與對照組比較,煤工塵肺偶髮室性早搏組及頻髮性室性早搏組TO值升高、TS值降低,差異有統計學意義(P＜0.05);與偶髮室性早搏組比較,頻髮室性早搏組TO值升高、TS值降低,差異有統計學意義(P＜0.05).結論 煤工塵肺患者頻髮性室性早搏組自主神經功能受損嚴重,HRV、HRT異常可作為評價煤工塵肺患者頻髮室性早搏的預後指標.

Objective To determine the predicative significance of HRV and HRT to premature beat on patients with coal-worker's pneumoconiosis.Methods 100 coal-worker's pneumoconiosis patients with premature beat (including 44 cases of occasional ventricular premature contraction and 56 cases of frequent ventricular premature contraction) were chosen as CWP group,and 50 healthy coal workers were chosen as control group.24 h DCG was used to monitor and analyze the change of premature beat and to calculate HRV.Index:SDNN,SDANN,HFLF,HRT:TO,TS,compare HRV of CWP group and control group and the changes of HRT of both occasional and frequent ventricular premature contraction.Results The incidence of CWP at night (66.1％,37 cases)is higher than that during daytime (33.9％,19 cases),and the difference is statistically significant with P＜0.05.HRV(SDNN SDANN HF HL) indexes of CWP group are lower than control group,and the difference is statistically significant with P＜0.05.HRV indexes of control group at night are higher than that during daytime,and the difference is statistically significant with P＜0.05.Comparison of CWP group HRV indexes between day and night is statistically insignificant with P＞0.05.Compared with control group,TO of CWP group is higher while TS is lower,and the difference is statistically significant with P＜0.05.Compared with occasional ventricular premature contraction patients in CWP group,TO of frequent ventricular premature contraction patients is higher while TS is lower,and the difference is statistically significant with P＜0.05.Conclusion Frequent ventricular premature contraction group in CWP group suffer from severe impaired autonomic nervous function injury,and abnormal HRV and HRT can be prognostic indicator of frequent ventricular premature contraction among coal-worker' s pneumoconiosis patients.
