经食道心房调搏对预激综合征电生理检查的临床应用

CLINICAL APPLICATION OF TRANSESOPHAGEAL ATRIAL PACING IN ELECTROCARIO —PHYSIOLOGICAL EXAMINATION OF W-P-W SYNDROME

对10例 W-P-W 患者经食道调搏进行了电生理检查,测定的ERP_(AP)为276.6±43.2ms,其中3例为具有潜在危险性的短 ERAp(<270 ms);4例为隐匿型 W-P-W;4例经调搏诱发了室上速发作;对1例 W-P-W 患者进行了药物观察试验。对有关的问题进行了讨论。

Electrocardio-physiological examinations in 10 patients of W-P-W sy-ndrome were made.The ERP_(Ap) was 276.6±43.2ms (S1S1) .Three ofthese Patients were of short-ERP_(Ap) which was potentially dangerous.Four of them suffered from latent W-P-W syndrome.In 4 patients,PSVT was evoked by transesophageal atrial pacing.Some problemsconcerning W-P-W syndrome were discussed.
