目的评价超声心动图、动态心电图的特点及部分重要体征在预测肥厚性心肌患者发生恶性心律失常甚至猝死等严重临床事件中的价值。方法回顾性分析48例在我院经超声心动图诊断的肥厚性心肌患者,所有患者经超声心动图确诊并排除高血压、主动脉瓣狭窄等引起的心室继发性肥厚,并有动态心电图检查报告,超声心动图测量数据包括左室长轴切面、大动脉短轴切面测量的厚度、脉冲多普勒测左室流出道压力阶差、分别有无左室流出道梗阻,动态心电图分析采用世纪今科12导联动态分析仪。结果间隔肥厚梗阻组较其他组更容易出现QT间期延长,心房颤动,短阵室速及晕厥的发生(P<0.01)。结论本组肥厚型心肌患者提示发生晕厥等严重临床事件的预测因素有多点。
Objective To evaluate the characteristics of echocardiography and ambulatory electrocardiogram (ECG) and some important signs in the prediction of severe clinical events such as malignant arrhythmia and sudden death in patients with hypertrophic myocardium. Methods A retrospective analysis of 48 cases of hypertrophic myocardium diagnosed by echocardiography in our hospital, all patients confirmed by echocardiography and exclude hypertension, aortic stenosis caused by ventricular secondary hypertrophy, and dynamic electrocardiogram Report, echocardiographic measurement data, including the long axis of the left ventricular section, the thickness of the short axis of the aorta measured by pulsed Doppler left ventricular outflow tract pressure gradient, respectively, with or without left ventricular outflow tract obstruction, Holter analysis using century Section 12-lead dynamic analyzer. Results Intermittent hypertrophic obstruction group were more likely than other groups QT prolongation, atrial fibrillation, paroxysmal ventricular tachycardia and syncope occurred (P <0.01). Conclusion This group of patients with hypertrophic myocardium prompted the occurrence of syncope and other serious clinical predictors of how many factors.
