[Endocardial mapping in the differential diagnosis of supraventricular arrhythmias].
The surface ECG only in a restricted number allows evidence on the course off conduction in the atria. By introduction of the intracardial electrography into the clinic as well as various stimulation techniques has become possible better to analyse the formation of stimuli and the conduction system in man. The diagnosis of supraventricular arrhythmias renders particular difficulties. By recording of the intracardial potentials in as many as possible and defined points of the atria in relation to the fixed point possibly near to the sinus node (endocardial mapping) a better analysis of the excitation and conduction is possible. Only own examinations on 9 patients with sinus rhythm and supraventricular dysrhythmias by means of atrial mapping showed that origin and course of the conduction of cardial arrhythmias may be clarified better. The method mentioned according to our experiences hitherto made and reports in literature despite several lacks and difficulties in an enrichment of the diagnostic possibilities in supraventricular dysrhythmias.
