摘要
为提高逆行P波(p^-波)检出率,用食管调搏法和常规心电图法对比观察37例隐匿性旁道参与的室上性心动过速患者Ⅰ、Ⅱ、V_1导联p^-波的检出率和极性确定率。结果提示:食管调搏法的p^-波检出率和极性确定率(100％、100％)远高于常规心电图法(46.8％、36.9％)(P<0.01)。认为食管调搏是鉴别室上速机制和无创伤定位隐匿性旁道的简便、可靠的手段。
In order to improve recognition rate of retrograde P wave (P-wave) , we used esophageal pacing and conventional electrocardiogram respectively to recognize P- wave and to identify polarity of P- wave in lead Ⅰ , Ⅱ and V1 in 37 patients with supraventricular tachycardia (SVT), utilizing a concealed atrioventricular accessory pathway. Results showed that recognition rate of P- wave and identification, rate of P- wave polarity with use of esophageal pacing (100%, 100%) were significantly higher than those by conventional electrocardiogram (46. 8%, 36. 9%) (P <0. 01). We thus concluded that esophageal pacing was a reliable means for distinguishing mechanism of SVT and non-traumaticly localizing concealed accessory pathways.
