The incidence of ventricular fibrillation with various contrast media (CM) was assessed by canine right coronary arteriography. After the catheter was impacted into the right coronary artery, it was infused continuously with CM for 25 seconds or until fibrillation occurred. The incidences of ventricular fibrillation were significantly higher with high-osmolality CM and low-osmolality CM without sodium ions than with low-osmolality CM containing a physiologic amount of sodium ions. The incidence of ventricular fibrillation was suggested to be related to hyperosmolality and the absence of sodium ions even in low-osmolality CM.
通过犬右冠状动脉造影评估了使用各种造影剂（CM）时室颤的发生率。将导管插入右冠状动脉后，持续注入造影剂25秒或直至发生室颤。高渗造影剂和不含钠离子的低渗造影剂导致的室颤发生率显著高于含有生理量钠离子的低渗造影剂。即使在低渗造影剂中，室颤的发生率也被认为与高渗以及缺乏钠离子有关。
