摘要 目的:探究急性心肌梗死(AMI)患者心电图碎裂QRS波与左心室心肌收缩功能的相关关系。方法:收集本院2019年1月~2023年1月收治的184例AMI患者临床资料。按照心电图QRS波形态分组,分为碎裂QRS波组72例,非碎裂QRS波组112例。比较两组一般资料:年龄、性别、体重指数(BMI)、吸烟、高血压、糖尿病、左室射血分数、左心室舒张末期内径,斯皮尔曼相关性分析AMI患者心电图碎裂QRS波与左心室心肌收缩功能的相关关系。结果:两组一般资料比较差异无统计学意义(P>0.05)。碎裂QRS波组左室射血分数低于非碎裂QRS波组,左心室舒张末期内径高于非碎裂QRS波组,差异显著(P>0.05)。AMI患者心电图碎裂QRS波与左室射血分数呈负相关关系(r=-0.615,P<0.001),与左心室舒张末期内径呈正相关关系(r=0.587,P<0.001)。结论:AMI患者心电图碎裂QRS波与左心室心肌收缩功能异常有关,与左心室射血分数呈负相关,与左心室舒张末期内径呈正相关。
