title: [Difficulties with pharmacologic treatment of a patient with atrioventricular nodal reentrant tachycardia].
abstract: A case history of a 38 year old teacher with AVNRT is described. She had been treated for 11 years with 11 antiarrhythmic drugs in various combinations. No treatment prevented recurrence of arrhythmia. During long term treatment with class IA, IC, II, III and IV antiarrhythmic drugs, various side effects occurred. There was also suspicion of proarrhythmic effect, especially of prajmaline. Some of the drugs terminated tachycardia while administered intravenously. But often deep hypotonia, heart automatism disturbances and even asystole occurred, MAS syndrome occurred 5 times. The patient was referred to our laboratory to perform percutaneous radiofrequency ablation of the slow pathway. The procedure was performed without any complications. Efficacy of the ablation was proved by electrophysiologic study before and after intravenous atropine administration. During the 11 months follow-up the patient had no tachycardia. She is on no antiarrhythmic medication and continues her normal activity.
