探讨心电图碎裂QRS波与急性心肌梗死患者室性心律失常及左心室收缩功能的相关性。

选取2015年1月至2017年1月无锡市中医医院收治的急性心肌梗死患者150例，依据其12导心电图QRS波形态进行分组，A组(n＝50，碎裂QRS波)，B组(n＝50，病理性Q波)，C组(n＝50，碎裂QRS波合并病理性Q波)。比较分析3组的室性心律失常及左心室收缩功能的相关性。

B组ⅣA级、ⅣB级、Ⅴ级室性心律失常发生率明显低于A组、C组(P<0.05)；B组的LVDD低于A组、C组(P<0.05)，而LVEF高于A组、C组(P<0.05)。

急性心肌梗死患者心电图碎裂QRS波与室性心律失常有关，且患者的左心室收缩功能显著降低。

To investigate the correlation between ventricular arrhythmias and left ventricular systolic function in patients with acute myocardial infarction (ecg).

Select 150 cases of patients with acute myocardial infarction (mi) into the study, and based on the grouping of 12-lead electrocardiogram QRS wave form, divided into group B (n=50, pathologic Q wave), group A (n=50, fragmented QRS wave), group C (n=50, cataclastic QRS wave merging pathologic Q wave). The correlation between ventricular arrhythmia and left ventricular systolic function was analyzed.

Group B Ⅳ grade A and B Ⅳ, Ⅴ incidence of ventricular arrhythmia was lower than that in group A and group C(P<0.05); The LVDD in group B was lower than group A and group C (P<0.05), while LVEF was higher than group A and group C (P<0.05).

The electrocardiogram of patients with acute myocardial infarction was associated with ventricular arrhythmias, and the left ventricular systolic function decreased significantly.
