[Electrophysiologic properties of diltiazem VUFB tablets: effect on atrioventricular conduction]. / Elektrofyziologické vlastnosti diltiazemu VUFB tablety: vliv na atrioventrikulární prevod.

The authors investigated the action of a single oral dose of the recently developed preparation Diltiazem VUFB tabl. on electrophysiological parameters of atrioventricular conduction - the AH, HV interval, Wenkebach's point and the relative, functional and effective refractory period of the atrioventricular node. The preparation affects significantly parameters of the level of the node and its effect is comparable with data on the action of diltiazem produced abroad.
