【摘要】 目的 :探讨慢性肺心病并发心律失常的发生率及其主要原因。方法 :对 5 0例肺心病患者应用美国麦克 85 0 0 T系统磁带式记录仪 ,MV5和 MV1双极导联连续同步监测 2 4小时 ,并分别在 2 4小时持续低流量吸氧及非吸氧下监测。结果 :(1)动态心电图 (DCG)检出心律失常 32例 ,占 6 4%(32 / 5 0 ) ,常规心电图检出心律失常 16例 ,占 32 %(16 / 5 0 ) ,两组有明显差异 (P<0 .0 5 ) ;(2 )吸氧组 2 0例 ,DCG检出心律失常 6例 ,占 30 %;非吸氧组 30例 ,DCG检出心律失常 2 6例 ,占 86 %,两组有明显差异 (P<0 .0 5 ) ;(3)血氧分析 :吸氧组氧分压均值为 10 .37k Pa,二氧化碳分压均值为 6 .6 5 k Pa;非吸氧组氧分压均值为 8.5 k Pa,二氧化碳分压均值为 7.4k Pa,两组有显著差异 (P<0 .0 5 )。结论 :结果说明 ,(1)动态心电图 2 4小时连续监测发现的慢性肺心病心律失常发生率明显高于常规心电图发现的心律失常发生率 (P<0 .0 5 ) ;(2 )肺心病心律失常的发生与低氧血症、高碳酸有密切关系 ;(3)对于慢性肺心病人动态心电图监测和吸氧治疗是非常重要的。更多还原

【Abstract】 Objective:To study the incidence and reason of arrhythmia in patients with chronic pulmonary heart disease(CPHD).Methods:Fifty CPHD patients were monitored in persistent oxygen uptake and non-oxygen uptake for 24 hours by MV5 and MV1 bipolar leading of MIKE 8500 tape-recorder.Results:(1)Patients with arrhythmia complicated in CDHD were 32 cases(64%) discovered by DCG and it were 16 cases(32%) discovered by routine ECG,there was significant difference(P<0.05);(2)Arrhythmia patients complicated in CPHD in oxygen uptake group (20 cases) were 6 cases (30%) and non-oxygen uptake group (30 cases) were 26 cases(86%),P<0.05;(3)The average PaO 2 was 10.37 kPa and PaCO 2 was 6.65 kPa in oxygen uptake group, PaO 2 was 8.5 kPa and PaCO 2 was 7.4 kPa in non-oxygen uptake group(P<0.05).Conclusion:The results indicate that,(1)The incidence of arrhythmia in patients with CPHD by DCG is higher than by routine ECG;(2)There is close relationship among arrhythmia and hypoxemia,hypercapnemia;(3)DCG monitoring and oxygen therapy are very important in patients with CPHD.更多还原
