Effects of verapamil on accessory pathway properties and induction of circus movement tachycardia in patients with the Wolf-Parkinson-White syndrome.

abstract：:Several 3,5-pyridinedicarboxylic acid [4-(2,3-dichlorophenyl)-1,4-dihydro-2,6-dimethyl-] esters, which are analogs to felodipine, were synthesized and tested for peroral activity and vascular selectivity. Structure-activity relationships demonstrate that felodipine has biological properties (selectivity and oral activ...
