title: [Accentuated anterior and posterior orientation--2 newly defined disorders of impulse conduction of the heart distal to the AV node].
abstract: During a programmed atrial stimulation in 80% of the cases disturbances of the stimulus conduction could be produced distally to the atrioventricular node. In the horizontal plane of the vector cardiogram two different configurations appeared. In 45 examinations an anterior displacement and in 36 examinations a posterior displacement of the vector loop could be evoked. Issuing from this, in healthy persons in 44 cases vector cardiograms with an emphasized anterior orientation (AD) and 21 cases with an opposite configuration of an emphasized posterior orientation (PD) were compiled. The criteria for the two up to now little or not described disturbances of the stimulus conduction are presented. It is referred to the extension of the principles of the subdivision of the disturbances of the stimulus conduction.
