目的通过分析患者年龄、冠状动脉病变支数与心脏变时性的相关关系,探讨动态心电图评价冠心病(CHD)患者的心脏变时性功能不全(CI)的临床意义和心脏变时性功能不全在判断冠状动脉病变及其严重程度中的价值。方法运用动态心电图检测我院126例临床拟诊CHD患者心脏变时性功能不全的情况。结果①CHD组中心脏变时性功能不全发生率明显高于对照组;②CHD组中老年组心脏变时性功能不全发生率明显高于中年组;③CHD伴三支病变者心脏变时性功能不全发生率显著高于伴单、双支病变者。结论①CHD患者可能存在显著的心脏变时性功能不全;②CHD患者的年龄可能是导致心脏变时性功能不全的主要因素之一,≥65岁老年CHD患者存在显著的心脏变时性功能不全;③CHD患者心脏变时性功能不全与冠脉病变程度(支数)相关。
Objective To investigate the clinical significance of dynamic electrocardiogram (ECG) in assessing cardiac time-deficit (CI) in patients with coronary heart disease (CHD) and analyze the relationship between cardiac tachyarrhythmia In determining the severity of coronary artery lesions and its value. Methods Using dynamic electrocardiogram to detect 126 cases of clinical CHD patients with cardiac chronotropic dysfunction in our hospital. Results ① The incidence of cardiac dysfunction in CHD group was significantly higher than that in control group; ② The incidence of cardiac dyskinesia in CHD group was significantly higher than that in middle-aged group; ③ CHD with cardiac dysfunction The incidence was significantly higher than with single, double-vessel disease. Conclusion ① There may be significant cardiac chronotropic dysfunction in patients with CHD. ② The age of patients with CHD may be one of the major factors that cause chronotropic dysfunction in the heart, and there is significant cardiac chronotropic dysfunction in CHD patients aged 65 or older. ③DCH Chronic cardiac dysfunction in patients with coronary artery disease (degree) related.
