目的探讨头胸导联在右室疾病诊断中的应用价值。方法通过对36例急性下壁梗死患者、40例右室肥大患者和20例健康对照者同时行头胸导联(HC导联)和常规导联右室心电图作对比分析。结果发现HC导联较常规导联对于急性下壁梗死合并右室梗死的检出率和右室肥大诊断的准确性、敏感性均明显提高(两者分别为P<0.05和P<0.01)。结论HC导联对右室疾病的诊断明显优于常规导联,可降低误诊率和漏诊率。
Objective To explore the value of head-chest lead in the diagnosis of right ventricular disease. Methods Thirty-six patients with acute inferior wall infarction, 40 patients with right ventricular hypertrophy and 20 healthy controls underwent simultaneous chest radiography (HC) and routine guided right ventricular electrocardiogram (ECG). The results showed that the lead of HC lead was significantly higher than the conventional leads in detecting acute right inferior wall infarction complicated with right ventricular infarction and right ventricular hypertrophy, both of which were P <0.05 and P <0.01 respectively. Conclusion HC lead diagnosis of right ventricular disease was significantly better than the conventional lead, can reduce the misdiagnosis rate and missed diagnosis rate.
