title: [The prognosis of the transitory disturbances of av-conduction following cardiac surgery (author's transl)].
abstract: Out of 2250 cases with open heart surgery 106 patients were examined because of disturbances of av-conduction in the Department for Cardiology of the Childrens Hospital of the University of Göttingen. 38, 7 percent of all av-conduction disturbances have persisted, whereas 61, 3 percent were reversible. Especially the ventricular septal defects, the tetralogy of Fallot and the endocardial cushion defects are discussed. These lesions are predisposed for postsurgical av-disturbances because they are near to the av-conduction tissue. In this paper it has been demonstrated that the av-conduction disturbances, which last for more than one week, have only a little chance to return to sinus rhythm. Those which endure more than four weeks, will persist. The longer the av-conduction disturbances are lasting, the less is the possibility for restitution of sinus rhythm.
