| | This paper was to observe the anti-interference action of AAM-II type wireless remote EKG metering and tape recorder which was made by the physical department of Chongqing Medical College. 40 patients were selected for observation.EKG of those patients were measured at different distance and under the following conditions, intake I131; contacted indium113m; under ultrashort wave, ultrared and remote ultrared rays. The results showed that all waves of EKG were no alternation, no interference and ... | | 本文为观察重庆医学院物理教研室研制的AAM-Ⅱ型无线心电遥测和磁带记录仪对干扰的影响。对40例患者分别在1-150m远距离描记,摄入~131碘或直接接触~113m铟、~60CO照射及50—250w超短波电疗机,红外线、远红外线下作不同距离描记。三种描记结果显示不改变各组心电图图形,亦无干扰,图像清晰。监测结果表明,该机对放射性同位素、理疗机等电光波具有高保真,并且有强大的抗干扰性能。 | | 文摘来源 | | 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 ... | | 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... | | 文摘来源 | |   |
