Toxicity studies of coronary arteriographic media in dogs.

Investigative Radiology
R S Frech

Abstract

Sequential injections of different contrast material in the canine coronary artery were performed while ventricular pressure and EKG were recorded. Larger volumes of contrast material caused more fibrillation and more drop in pressure. Preliminary myocardial infarction increased pressure effects. Diatrizoate methylglucamine (Renografin-76) caused more fibrillation and lowering of ventricular pressure than iothalamate or metrizoate Coronar. Calcium lessened the ventricular pressure depression from iothalamate.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
