A 68-year-old female patient with borderline QT prolongation developed polymorphic ventricular tachycardia soon after intracoronary injection of ioxaglate. There was no coronary stenosis or vasospasm. To investigate abnormality of the ventricular repolarization, we recorded the monophasic action potential (MAP) during coronary angiography. Ioxaglate prolonged the MAP duration regionally in the perfused area and produced temporal dispersion of ventricular repolarization.
一名68岁女性患者，QT间期临界延长，在冠状动脉内注射碘克沙醇后不久发生多形性室性心动过速。冠状动脉无狭窄或痉挛。为研究心室复极异常，我们在冠状动脉造影期间记录了单相动作电位（MAP）。碘克沙醇使灌注区域局部MAP时程延长，并导致心室复极的暂时性离散。
