Abstract

During an electrophysiological study in a patient with a concealed accessory connection, there was no evidence of electrical or mechanical alternans during tachycardia until propranolol was administered, but both forms of alternans developed with tachycardia of a slower rate following propranolol. Echocardiographic, arterial pressure, and electrocardiographic data obtained prior to and following propranolol administration are presented.

摘要

在对一名隐匿性房室旁道患者进行电生理研究期间，在给予普萘洛尔之前，心动过速时未出现电交替或机械性交替的证据，但在给予普萘洛尔后，随着心率减慢的心动过速出现了两种交替形式。本文展示了给予普萘洛尔前后获得的超声心动图、动脉压和心电图数据。
