Hyoscine-B butyl bromide in labor: a randomized controlled trial.

In our case, dipyridamole-induced ischemia is an unlikely cause. This may suggest the depressive action of dipyridamole through adenosine on the conducting system. We feel that dipyridamole is the probable cause of asystole in this individual, based on a score of 5 on Naranjo’s algorithm, and betablocking agents may have contributed to this.[6] In patients with underlying conduction abnormalities or bradycardia or in those undergoing concomitant beta-b locker administration, a reasonable caution should be exercised before administrat ion of dipyridamole.
