title: [Indication for preventive pacemaker implantations in patients with severe disorders of atrioventricular conduction].
abstract: A method for the evaluation of patients with severe conduction disturbances who might develop Adams-Stokes attacks or total A-V block is described. In 9 patients with conduction disturbances a "stress test" of the conduction system with small dosis of Ajmalin was performed. In 2 patients a higher degree of A-V block developed (2: 1 block, total A-V block). These patients were considered as candidates for prophylactic pacemakerinsertion. During this procedure a temporary pacemaker electrode has to be put into the right ventricle to provide saftey for the patient.
