摘要
目的探讨常规心电图对局灶性房性心动过速起源部位的预测情况。方法采用回顾性分析的方法,分析我院收治的80例局灶性房性心动过速患者心电图资料。结果患者常规心电图诊断局灶性房速起源部位和临床证实无明显差异(χ2=0.28,P>0.05);V1导联房性P波负向或正负双向预测右房房速的特异性为100%,敏感性为95%;Ⅰ导联和aVL导联P波负向预测左房房速的特异性分别达到了97%和92%,但敏感性分别仅有32%和50%。结论常规心电图P波可以初步诊断局灶性房性心动过速起源部位,同时还应结合病史、发作时的临床表现及心电图的特点进行诊断与鉴别诊断。
Objective To study the ECG on the origin of focal atrial tachycardia parts of the projections. Methods Retrospective analysis, analysis of 80 patients in our hospital in patients with focal atrial tachycardia ECG data. Results ECG diagnosis in patients with focal atrial sites and places of origin showed no significant differences in clinical （P 〉 0.05 ） ; V1 lead atrial P wave negative or positive and negative bi-directional prediction from right atrial rate was 100%, sensitivity was 95%; I lead and aVL leads to prediction of negative P wave velocity of left atrial specificity were 97% and 92%, respectively, but sensitivity of only 32% and 50%, respectively. Conclusion ECG P wave can be an initial diagnosis of focal atrial tachycardia site of origin, should also be combined with medical history, onset of clinical manifestations and the characteristics of ECG diagnosis and differential diagnosis.
