目的 :探讨急性心肌梗死 (AMI)墓碑形ST段抬高的临床意义。方法 :将 4 4例前壁AMI分为两组 :①ST段呈墓碑形抬高组 (A组 ,11例 )。②ST段呈常态形抬高组 (B组 ,33例 )。对两组的心电图 (ECG)及临床资料进行比较并做统计学处理。结果 :两组的ECG :nST、ΣST、nQ、ΣQ、ndT、Tmax差异均有显著性意义 ,A组的ST Tom STmax与ST Tom Tmax存在强相关性 ,ST Tom dt与ST ct分别为 (6 .4 8± 2 .4 5 )h、(10 .5 0± 7.2 0 )d。两组的临床资料除肌酸激酶外 ,心功能分级、并发症、危险因素等均差异无显著性意义。两组近期无一例死亡。结论 :并非所有ST呈墓碑形改变的AMI患者近期预后均较凶险
Objective: To investigate the clinical significance of tombstoning ST-segment elevation in acute myocardial infarction (AMI). Methods: The AMI of 44 cases of anterior wall were divided into two groups: (1) ST segment was tombstoned (group A, 11 cases). ②ST segment showed normal shape elevation group (group B, 33 cases). The two groups of ECG and clinical data were compared and statistically analyzed. Results: There was a significant difference between the two groups in the ECGs: nST, ΣST, nQ, ΣQ, ndT and Tmax. There was a strong correlation between ST Tom STmax and ST Tom Tmax in group A, and ST Tom dt and ST ct were (6 .4 8 ± 2 .4 5) h, (10 .5 ± 7.2 0) d. Clinical data of two groups except creatine kinase, cardiac function classification, complications, risk factors were no significant difference. Two recent deaths without a case. CONCLUSIONS: Not all patients with AMI presenting with gravestone-shaped changes are more likely to have near-term prognosis
