Abstract
In 30 patients undergoing coronary angiography the effects of lopamidol on sinus node activity, atrioventricular and intraventricular conduction were evaluated using His Bundle recordings, and compared to the effects produced by Diathzoate.
Diatrizoate resulted in an increase in sinus cycle length and prolonged AV nodal conduction, resulting in second degree A V block in two patients, lopamidol had significantly less effect on sinus cycle (P<0.01) and AV nodal conduction (P<0.01). Neither contrast media affected intraventricular conduction. No difference was noted in the imaging power of the two contrast media.
It is suggested that non-ionic, low osmotic contrast media such as lopamidol will result in increased patient safety during coronary angiography without loss of imaging power.
