室性心律失常患者随访期间进行动态心电图(AECG)监测可提供定量资料,然而使用不便且费用昂贵,故只能定期复查,非监测期间发生的严重心律失常难免漏检.心电图电活传真(TECG)提供“实时”信息,理论上可以充当心律失常监测系统.本文以AECG为基准方法,分析TECG(每次3分钟)检出和预报室性心律失常及其复发的准确性.试验Ⅰ.平均年龄56岁的24(男19、女5)例频繁的非持续性室(性心动过)速(24小时AECG记录1556±948阵/日,均值±标准误,下同)病人,使用抗心律失常药物moricizine每周3次.无症状期间TECG278次,未见室性早搏(132次)、1～5次室早(49次)、6～20次室早(44次)、21～100次室早(37次)和100次以上室早(16次),同时记录的AECG示每小时室早次数31±8、112±26、187±18、798±81和1298±142,每天室速阵数依次为0.7±0.3、10±2.9、27±9.6、229±64和479±150.经协方差分析示:TECG每小时室早次数、每小时
AECG monitoring during follow-up of patients with ventricular arrhythmias provides quantitative data, however, inconvenient and expensive to use and can only be reviewed on a regular basis and serious arrhythmias that occur during non-monitoring can not be underestimated. Electrocardiogram electro-active fax (TECG ) Provides “real-time” information which can theoretically be used as a cardiac arrhythmia monitoring system.This paper analyzed the accuracy of TECG (3 minutes each time) in detecting and predicting ventricular arrhythmia and its recurrence based on AECG.Experiment Ⅰ . A total of 24 (19 males and 5 females) patients with a mean age of 56 years underwent frequent non-sustained ventricular tachycardia (2456 AECG recording 1556 ± 948 males / day, mean ± standard error, the same below) The antiarrhythmic drug moricizine was administered 3 times a week, as many as TECG278 during asymptomatic periods, no premature ventricular contractions (132 episodes), 1 to 5 morning premature infants (49 episodes), 6 to 20 premature ventricular contractions (44) AECG was recorded at 31 ± 8,112 ± 26,187 ± 18,798 ± 81 and 1298 ± 142 hours per 100 cases in 100 premature infants (37 times) and 100 times premature infants (16 times) The VTs were 0.7 ± 0.3, 10 ± 2.9, 27 ± 9.6, 229 ± 64, and 479 ± 150, respectively. Analysis by covariance showed that TECG was earlier for each hour,
