Application of His bundle recording in different rhythm disturbances of the heart.
The new intracardiac electrophysiological method: His bundle electrocardiography, combined with the electrophysiological examination used in routine clinical practice, has considerably improved our knowledge of the cardiac dysrhythmias. It helps to localize the focus of the atypical junctional and other supraventricular premature beats complicated with either organic or functional intraventricular conduction disturbance. The various forms of paroxysmal tachycardias can be differentiated more exactly from each other. In pre-excitation syndrome, it has become possible to detect the abnormal pathway and to screen the patients susceptible to life-threatening arrhythmias. By means of this the diagnosis of sick sinus syndrome and estimation of its severity can be made more exactly. In addition to the diagnosis, the electrophysiological examinations connected with pharmacological tests give valuable information whether medical or pacemaker therapy should be applied. Six cases of various forms of cardiac dysrhythmias are presented to demonstrate the superiority of this method.
