食管心房调搏诊断预激综合征宽QRS心动过速

A diagnosis of preexcitation syndrome with wide-QRS tachycardia using transesophageal atrial pacing

用食管心房调搏结合多导同步描记术对33例预激综合征伴宽 QRS 心动过速进行电生理检查。提出了反向型房室折返性心动过速和正向型房室折返性心动过速伴束支传导障碍的食管调搏诊断标准。讨论了这些标准在诊断和鉴别诊断上的意义与局限性。

Electrophysiologic tudies of 33 cases of preexcitation syndrome with wide-QRStachycardia using transesophageal atrial pacing combined with simultaneous multichannel record-ing method were reported.The authors attempt to build up the electophysilolgica diagnsotic crite-ria of antidromic atriovintriacular reciprocating tachycardia and orthodromic atrio-ventricular re-ciprocating tachycardia with bundle branch conduction disturbance.Significance and limitation ofthese criteria in diagnosis and differential diagnosis were discussed.
