| 目的 比较分析肥厚型心肌病的诊断中超声心动图与心电图的灵敏性和特异性。方法 选取我院门诊患者进行研究,以磁共振成像作为金标准诊断梗阻性肥厚型心肌病患者30例,非梗阻性肥厚型心肌病患者70例。计算分析梗阻性与非梗阻性肥厚型心肌病的诊断中超声心动图与心电图的灵敏性和特异度等指标。结果 综合分析超声心动结合多普勒组织成像技术、超声心动和心电图三种诊断方法对于诊肥厚型心肌病的灵敏度未见差别,其灵敏度分别为96.00%、96.00%和94.00%；特异度以心电图诊断方式的最低,超声心动结合多普勒组织成像技术诊断特异度最高。超声心动图技术在诊断梗阻型肥厚性心肌病中灵敏度最高。特异度比较结果提示,心电图诊断的特异度最低。而在诊断非梗阻性肥厚型心肌病中,超声心动结合多普勒组织成像技术诊断灵敏度高。三种诊断方法无论在诊断梗阻与非梗阻性的肥厚型心肌病中,均可见阳性和阴性预测值的差别,综合分析中表现出心电图诊断的水平低于其他两种方式。结论 传统心电图诊断的水平低于其他两种方式的特点,超声心动图可以直接看到心脏的各组织,可通过测量数据,以利临床诊疗。 |

| Objective To discuss the sensitivity and specificity of ultrasonography and electrocardiogram technology for hypertrophiccardiomyopathy.Methods Hospital outpatient study was conducted in this manuscript,and use the magnetic resonance imaging as the gold standard.30 cases of non-obstructive hypertrophic cardiomyopathy 70 cases were included.Comparison for diagnosis of obstructive and non-obstructive hypertrophic cardiomyopathy was discussed,sensitivity and specificity of the ECG and ultrasound technology and other technical indicators were analyzed at the same time.Results The comprehensive analysis of echocardiography combined with Doppler tissue imaging,echocardiography and ECG showed no difference for the three diagnostic methods,the sensitivity,was 96.00%,96.00% and 94.00%; Echocardiographic techniques obtained the highest sensitivity in the diagnosis of obstructive off hypertrophic cardiomyopathy.Specificity value for ECG diagnostic showed to be the lowest one.In the diagnosis of non-obstructive hypertrophic cardiomyopathy,ECG diagnosis is lower than the other two methods for specificity status.Three diagnostic methods showed differences in positive and negative predictive values also,ECG diagnosis exhibited the lowest level in these values.Conclusion The different methods for the diagnosis of hypertrophic cardiomyopathy obtained different characteristics,suggesting that the value of traditional ECG diagnosis is less than the ultrasonography. |
