May support nifedipine where AV preservation matters; leaves open randomized confirmation in conduction disorders.
Does intravenous nifedipine affect atrioventricular conduction compared to verapamil in patients undergoing intracardiac electrophysiological studies?
Unlike verapamil, intravenous nifedipine does not depress atrioventricular conduction, suggesting it is safe for patients with AV nodal conduction disorders or those on beta-blockers.
Rowland et al. (1979) studied this question.
