分析脑卒中急性期患者QT间期离散度变化与室性心律失常的关系。
选取2016年5月至2017年10月寿光市人民医院收治的脑卒中急性期患者80例及同期在同医院体检的中老年健康体检者40例为研究对象。根据脑卒中类型的不同，将其分为A组(出血性脑卒中，32例)、B(缺血性脑卒中，48例)2个组别。40例健康体检者均纳入C组。分别给予3组行心电图仪检测，给予两组脑卒中患者心电监护仪监测。观察3组QT间期离散度差异、脑卒中急性期患者的室性心律失常发生率及QT间期离散度差异。
A组QT间期离散度显著高于B组、C组(P<0.05)，B组与C组比较，差异无统计学意义(P>0.05)。A组室性心律失常发生率高于B组(P<0.05)；室性心律失常组脑卒中急性期患者的QT间期离散度，显著高于正常脑卒中急性期组患者，差异有统计学意义(P<0.05)。
出血性脑卒中患者的室性心律失常发生风险较高。如发现脑卒中急性期患者伴有QT间期离散度异常增加，应警惕室性心律失常。
The relationship between the change of QT dispersion and ventricular arrhythmia in patients with acute stroke was analyzed.
A total of 80 acute stroke patients treated at the People′s Hospital of Shouguang City from May 2016 to October 2017 were selected and 40 middle-aged and elderly health checkups who were examined in the same hospital during the same period were selected as the study subjects. According to the type of stroke, they were divided into two groups: group A (hemorrhagic stroke, 32 cases) and B (ischemic stroke, 48 cases). All 40 healthy subjects were included in group C. Three groups of electrocardiographs were given for detection, and two groups of stroke patients were monitored by electrocardiograph. Observed the difference of QT interval dispersion, the incidence of ventricular arrhythmia and the dispersion of QT interval in patients with acute stroke.
The QT interval dispersion in group A was significantly higher than that in group B and C (P<0.05). There was no significant difference between group B and group C (P>0.05). The incidence of ventricular arrhythmia in group A was higher than that in group B (P<0.05). The QT dispersion in patients with acute stroke in ventricular arrhythmia group was significantly higher than that in patients with acute stroke in the acute group, and the difference was statistically significant. Significance (P<0.05).
Patients with hemorrhagic stroke have a higher risk of ventricular arrhythmias. If patients with acute stroke are associated with an abnormal increase in QT interval dispersion, they should be alert to ventricular arrhythmias.
