The incidence of cardiac arrhythmias during intravenous digital subtraction angiography: a comparison of peripheral and central injections.

Intravenous digital subtraction arteriography (IV-DSA) was carried out in 204 patients with arteriosclerotic peripheral vascular disease using the non-ionic contrast medium iopamidol 370. In 124 patients the injection was made into an antecubital vein and in 80 into the right atrium. Rhythm strip electrocardiograms showed no significant difference in incidence or type of arrhythmias between either injection method (p greater than 0.95).
