title: [Dynamic electrocardiography for identification of temporally altered activity in pacemakers (author's transl)].
abstract: Four cases of subjects with implanted pacemakers are reported. The patients temporarily presented suspected symptoms of altered activity of the pacemakers. On the other hand usual tests demonstrated a regular activity of the pacemakers. The dynamic electrocardiography, by a regular registration during 24/48 hours and during usual working, documented; once a partial hole in the circuits of the generator, twice a partial break of the catheter, once a displacement. It is underlined the importance of dynamic electrocardiography to identify temporarily altered activity of pacemakers, undiagnosticable by disposable usual tests.
