本文报道154例次心室造影术中造影剂注入心腔内瞬间的心电图改变,认为:1.注入时如出现房速、房早和/或P波形态改变,而无通常出现的短阵室速或室早,提示导管于注入瞬间退回心房;2.注入瞬间内通常出现的短阵室速、室早等均可于注射后自行消失,其本身并无重要临床意义;3.注入后即刻出现明显的ST-T改变,应警惕造影剂射穿心室肌.
This article reports 154 cases of sub-ventricular angiography contrast agent into the intracardiac electrocardiogram changes in the moment, that: 1. Infusion, such as the occurrence of atrial tachycardia, atrial premature beats and / or P wave morphological changes, and without the usual paroxysmal ventricular tachycardia Or room early, suggesting that the catheter in the injection of an instant return to the atrium; 2. Infusion usually appear within a moment of paroxysmal ventricular tachycardia, ventricular early and so on can disappear after injection, itself has no important clinical significance; Obvious ST-T changes, should be wary of contrast medium through the ventricular muscle.
