[Association of AV reciprocating tachycardia, using a concealed bundle of Kent, and paroxysmal atrial fibrillation in neurocardiogenic syncope].
A case of neurocardiogenic syncope is reported in which both AV-reciprocating tachycardia due to a concealed retrogradely conducting posteroseptal bypass tract and paroxysmal atrial fibrillation were observed. In connection with this case, attention is paid to the difficulties of differential diagnosis and to the pathophysiological correlations concerning the occurrence of neurocardiogenic/vasovagal reflex syncope and cardiac arrhythmias. A prolonged period of freedom from syncope and tachycardia was achieved by means of drug treatment, through the combined administration of disopyramide, bisoprolol and theophylline.
