title: [Diagnostic use of ajmaline and rapid ventricular stimulation in fascicular blocks].
abstract: For the provocation of trifascicular blockings in patients with fascicular block a rapid ventricular stimulation after an application of ajmalin of maximally 100 mg performed. Of 80 patients with clinically and electrocardiographically certain intermitting total atrioventricular blockings (group A) and 24 patients with typical anamnesis without ECG-proof of the atrioventricular block of higher degree (group B) altogether 88 patients had an atrioventricular block of 2nd or 3rd degree after provocation. On the other hand, only 2 of 20 patients with bifascicular block without syncopes (group C) had a positive result of the test. The method is regarded as suitable for the detection of trifascicular latent blockings.
