目的分析慢性肾脏病(CKD)患者肾功能衰竭期(CRF)的异常ECG检出率和ECG异常类型,探讨ECG对CRF患者并发心血管疾病(CVD)的临床诊断价值。方法选择CKD 4期和CKD 5期(暂未进行维持性血液透析)患者各80例,对每例患者进行ECG检查2次,并进行比较分析。结果 CKD 4期80例ECG异常115例次,异常检出率71.88%;CKD 5期ECG检测80例,异常123例次,异常检出率81.88%;两组异常ECG检出率比较,有统计学意义(P<0.05)。两组ECG异常类型比较,无统计学意义(P>0.05)。结论 CKD 5期患者并发CVD的风险性更大;两期患者ECG异常类型多样易变,出现不同程度ST-T改变、房室肥大、各类心律失常等异常,ECG结果可以作为无创伤性检查发现CVD并发症诊断的重要依据之一,有利于临床早诊断、早治疗。
Objective To analyze the abnormal ECG types and ECG abnormalities in patients with chronic kidney disease (CKD) during renal failure (CRF) and to investigate the clinical value of ECG in the diagnosis of cardiovascular disease (CVD) in patients with CRF. Methods Eighty patients with CKD stage 4 and CKD stage 5 (without maintenance hemodialysis) were enrolled in this study. Each patient was examined by ECG twice and analyzed comparatively. Results There were 115 cases of ECG abnormalities in 80 cases of CKD stage 4 and 71.88% of them were abnormal in CKD stage 4, 80 cases of CKD stage 5 ECG were detected in 123 cases and abnormality was detected in 81 cases. The detection rate of abnormal ECG was statistically significant Significance (P <0.05). There was no significant difference between the two groups in ECG abnormalities (P> 0.05). Conclusions There is a higher risk of concurrent CVD in stage 5 patients with CKD. The types of ECG abnormalities in two stages are variable and varied, with varying degrees of ST-T changes, atrioventricular hypertrophy and various types of arrhythmias. ECG results can be used as noninvasive examination Found that one of the important basis for the diagnosis of CVD complications, is conducive to clinical early diagnosis and early treatment.
