    In 30 patients undergoing coronary angiography the effects of Iopamidol on sinus node activity, atrioventricular and intraventricular conduction were evaluated using His Bundle recordings, and compared to the effects produced by Diatrizoate. Diatrizoate resulted in an increase in sinus cycle length and prolonged AV nodal conduction, resulting in second degree AV block in two patients. Iopamidol had significantly less effect on sinus cycle (P less than 0.01) and AV nodal conduction (P less than 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 Iopamidol will result in increased patient safety during coronary angiography without loss of imaging power.

    Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
