[The new calcium antagonist Ro 11-1781 in the treatment of ventricular tachycardia due to atrial fibrillation]. 1978

B Brisse, and F Bender, and H Gülker, and H Niehues

In 9 patients with tachyarrhythmia and atrial fibrillation the effect of the i.v. application of the calcium antagonist Ro 11-1781 on the av-conduction was investigated. All patients received 1 mg/kg during 2-3 minutes. A significant decrease of the ventricular rate at the end of the injection period was noted. The maximal decrease of the av-conduction of 10-32 % of the initial ventricular rate was observed 5-10 min after the injection. During 60 min the initial heart rate before application of the drug was not yet reached again. The registrations prove the inihibiting effect of Ro 11-1781 on av-conduction in atrial fibrillation, which was sufficient for therapeutic use in our cases concerning the reduction of heart rate and duration of the effect. No serious side effects were observed.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
