In twenty beagle dogs selective injections were made into the left coronary artery with iopentol, iohexol and metrizoate in doses of 4 ml, 8 ml and 16 ml. Thirty-six iopentol injections, 35 iohexol injections and 37 metrizoate injections were made. Frequencies of ventricular fibrillation were significantly lower (p less than 0.05) after iopentol (0%) and iohexol (3%) than after metrizoate (22%). Iopentol and iohexol also produced significantly less decrease in aortic blood pressure than metrizoate at the different doses.
