title: Time course alterations of QTC interval due to hypaque 76.
abstract: Sequential measurement of QT interval during left ventricular angiography was made 30 seconds and one, three, five and ten minutes after injection of hypaque 76. The subjects were ten patients found to have normal left ventricles and coronary arteries. Significant QTC prolongation occurred in 30 seconds to one minute in association with marked hypotension and elevation of cardiac output.
