目的通过分析105例妊娠期一过性心肌缺血和(或)心律失常的病例,并随机抽取105例心电图正常的产妇病历与之比较,重点了解妊娠期一过性心肌缺血和(或)心律失常的转归,与病理妊娠的关系,与分娩方式的关系,对分娩过程的影响,探讨其发生机制。方法对2003～2007年住院的105例妊娠期一过性心肌缺血和(或)心律失常病历进行回顾性分析,并随机抽取这五年中105例心电图正常的产妇病历与之比较。结果①105例妊娠期一过性心肌缺血和(或)心律失常与105例心电图正常的产妇比较,前者与病理妊娠不相关,P>0.05;②105例妊娠期一过性心肌缺血和(或)心律失常与105例心电图正常的产妇分娩方式比较,前者剖宫产明显多于后者,P<0.01;③分别去除2组的病理妊娠和自己强烈要求剖宫产者,一过性心肌缺血和(或)心律失常组因心脏因素而选择剖宫产的明显大于心电图正常产妇对照组,P<0.01。结论妊娠期一过性心肌缺血和(或)心律失常与病理妊娠不相关,其因心脏因素而选择剖宫产的明显多于心电图正常产妇对照组,建议妊娠期一过性心肌缺血和(或)心律失常的产妇应主要根据心功能选择分娩方式。过去认为妊娠期心电图出现“心肌缺血”改变是因为心电轴心左移或右移,导致非特异性的S-T段T波改变的解释不全面,有部分是心力储备不足所致。
Objective To analyze 105 cases of transient myocardial ischemia and / or arrhythmia during pregnancy and to compare 105 normal cases of electrocardiogram (ECG) maternal health records with emphasis on the understanding of transient myocardial ischemia and / The outcome of arrhythmia, the relationship with pathological pregnancy, the relationship with mode of delivery, the impact on labor process and the mechanism of its occurrence. Methods A retrospective analysis was performed on 105 cases of transient myocardial ischemia and / or arrhythmia during pregnancy admitted to hospital from 2003 to 2007. 105 cases of normal electrocardiogram maternal medical records in this five years were randomly selected for comparison. Results ① The 105 cases of transient myocardial ischemia and / or arrhythmia during pregnancy were compared with 105 cases of normal electrocardiogram. The former was not related to pathological pregnancy, P> 0.05. ②105 cases of transient myocardial ischemia and / or ) Arrhythmia and 105 cases of normal ECG normal delivery mode, the former was significantly more than the latter, cesarean section, P <0.01; ③ were removed two groups of pathological pregnancy and their strong demand for cesarean section, transient myocardial ischemia Blood and (or) arrhythmia group cesarean section was significantly larger than the ECG normal maternal control group, P <0.01. Conclusions Myocardial ischemia and / or arrhythmia during pregnancy is not related to pathological pregnancy. Cesarean section due to cardiac factors is obviously more than normal control group of ECG. It is suggested that transient myocardial ischemia in pregnancy and (Or) arrhythmia of the mother should be based on cardiac function delivery mode. In the past that the ECG appears during pregnancy “myocardial ischemia ” change is because the ECG axis shift left or right, leading to non-specific S-T segment T wave changes are not explained in part, in part due to inadequate physical memory.
