摘　　要：目的探讨左心室舒张功能减退与动态心电图改变之间的关系。方法筛选我院查体中心2010年1月至2012年6月行心脏彩超检查的患者,选取左心室舒张功能减退组患者58例,随机选取心脏超声检查正常的患者40例设为对照组,两组均行24 h动态心电图检查。结果左心室舒张功能减退组的ST-T动态改变35例(60.3%),发生各类心律失常32例(55%),与对照组比较差异有统计学意义(P<0.05)。结论心脏超声诊断左心室舒张功能减退,提示可能是心脏损伤的早期表现,由于临床患者往往没有任何症状或症状较轻,容易被忽视,造成漏诊。因此凡心脏超声诊断左心室舒张功能减退者,应再进一步行动态心电图检查,以明确诊断,及时治疗。Objective To explore the relationship between the hypofunction of left ventricular diastolic function and the changes of dynamic electrocardiogram （DCG）. Methods Among the patients who have accepted echocardiogram inspections in the physical examination center of our hospital from January 2010 to June 2012, select 58 cases with vestigial left ventricular diastolic function as ob- servation group while randomly choose 40 normal cases inspected by echocardiograms as control group. Carry out 24-hour DCG examinations for both of the two groups. Results Among the observation group, there existed 35 cases（60.3% ） with ST-T dynamic changes and 32 cases（55% ） with attacks of various arrhythmias. Comparing with the control group, the differences were statistically significant （P 〈 0.05 ）. Conclusion It hints at the possibility of early performance of heart injury when echocardiogram result indicates the hypofunction of left ventricular diastolic function. However, the heart in- jury is easy to he ignored and missed clinically, since patients are usually free of any symptom or suffer light ones. For the above reasons, we suggest DCG examination furtherly for patients with vestigial left ventricular diastolic function diagnosed by echocardiograms, in order to clarify the diagnosis and give timely treatment.
