目的探讨原发性高血压(EH)左室心肌重量指数(LVMI)与心律失常的关系。方法对100例EH和100例正常人24h动态心电图(DCG)和心脏超声资料进行对比分析。结果①轻、重度心肌增重组(A1、A2组)心律失常的发生有明显差异(P<0.05),且A2组室性心律失常发生率高于A1组(P<0.05),其余两类型相比,两组无差异(P>0.05);②EH伴左心室肥厚(LVH)组的心律失常的发生率明显高于非LVH组(B组)(P<0.01),且A2组较A1组心律失常发生率高(P<0.01)。结论EH者LVMI愈高心律失常愈易发生,LVMI与心律失常的发生呈正相关。
Objective To investigate the relationship between left ventricular myocardial mass index (LVMI) and arrhythmia in essential hypertension (EH). Methods The dynamic electrocardiogram (DCG) and echocardiographic data of 100 cases of EH and 100 cases of normal people were compared and analyzed. Results ① There was significant difference in arrhythmia between mild and severe myocardial infarction group (A1, A2) (P <0.05), and the incidence of ventricular arrhythmia in A2 group was higher than that in A1 group (P <0.05). The other two types of phase (P> 0.05). ② The incidence of arrhythmia in patients with left ventricular hypertrophy and left ventricular hypertrophy was significantly higher than that in non-LVH patients (P <0.01) The incidence of abnormalities was high (P <0.01). Conclusion The higher the LVMI of EH, the more arrhythmias occur, and the incidence of arrhythmia is positively correlated with LVMI.
