近年来由于Holter的临床应用和动态监测,对蛛网膜下腔出血(SAH)合并心电图异常两者之间的研究逐渐深入,尤其是病理学研究为SAH合并心电图异常提供了有说服力的组织学证据。现就SAH合并心电图异常的病因,病理、治疗及其预后综述如下。 一、SAH的心电图异常 常见的异常形态有高尖P波(在Ⅱ导>2.5mm),P-R间期缩短或延长,病理性Q波,ST段抬高或压低,T波直立,低下、双向成倒置,宽大或u波反向;传导障碍除P-R间期延长外,还可有结性心律和房室分离;其它心律失常有窦性心动过速,窦性心动过缓、房性期前收缩,室性期前收缩,Torsade de pointe室性心动过速,Q-T延长和房颤,也可合并心肌梗塞,严重者可发生室颤,
In recent years, due to the clinical application and dynamic monitoring of Holter, the research on SAH combined with ECG abnormality has been gradually deepened. In particular, the pathological study provides a convincing histology for SAH combined with ECG abnormalities evidence. Now SAH combined ECG abnormalities, pathology, treatment and prognosis are summarized below. First, SAH ECG abnormalities common abnormal shape of high-tip P wave (Ⅱ guide> 2.5mm), PR interval shortening or prolonged, pathological Q wave, ST segment elevation or depression, T wave upright, low, two-way Inverted, large or u-wave reverse; conduction disorder in addition to prolongation of PR interval, but also have nodules and atrioventricular separation; other arrhythmia sinus tachycardia, sinus bradycardia, atrial Contractions, ventricular contraction, Torsade de pointe ventricular tachycardia, QT prolongation and atrial fibrillation, myocardial infarction may also be combined, in severe cases can occur ventricular fibrillation,
