[Prophylaxis of supraventricular paroxysmal tachycardias on the basis of electrophysiologic examinations].
Paroxysmal supraventricular tachycardias (PSVT) were classified with regard to electrophysiologic criteria in 12 cases. In 6 patients the reentry circuit of the PSVT involved a concealed accessory connection, in 6 patients the reentry circuit was confined to the A-V node. Different antiarrhythmic drugs were administered orally over a 4 week period, the frequency of attacks and possible side effects were recorded. In patients with accessory pathway metoprolol (n = 3), ajmalin (n = 3), Aprindine (n = 1) and verapamil (n = 1) prevented the occurrence of PSVT. Verapamil, Ro 11-1781, metoprolol and digitalis were effective in A-V nodal reentry. PSVT could be prevented in all but one patient by at least one drug.
