Abstract

The occurrence of electrical alternans of the ST segment has been reported in patients with variant angina. The authors encountered a patient with typical electrical alternans of the ST segment in leads V4 through V6, which developed during percutaneous transluminal coronary angioplasty (PTCA) of the proximal left anterior descending artery. Hemodynamic pulsus alternans of the aortic pressure tracing was not observed during electrical alternans, and a Ca2+ blocker could not prevent this phenomenon during PTCA.

摘要

变异型心绞痛患者中曾有ST段电交替现象的报道。作者遇到一名患者，在经皮腔内冠状动脉成形术（PTCA）治疗左前降支近端时，V4至V6导联出现典型的ST段电交替。电交替期间未观察到主动脉压力描记图的血流动力学脉搏交替，且在PTCA期间钙通道阻滞剂无法预防此现象。
