His Bundle Electrocardiography and Clinical Electrophysiology

Abstract

The His bundle catheter, in use for only about six years, together with the capillary microelectrode, now provide electrophysiologists with data that not only jar the foundations of traditional electrocardiography but also provide the previously empirical interpretation of normal and abnormal cardiac rhythms with a more solid, scientific base. This well-edited volume of 20 chapters begins with "Anatomic Basis for Impulse Generation and Atrioventricular Transmission," by Lev and Bharati, and ends with "Prognostic Values in H-V Intervals," by Narula, Gann, and Samet. Sandwiched in between are chapters on His bundle electrocardiography that summarize current uses, interpretations, limitations; anatomy and electrophysiology of cardiac conducting systems; techniques for His bundle recordings and their limitations. His catheter recordings, previously used mainly for investigative work, are now clinically useful, providing more reliable diagnostic and prognostic information about cardiac arrhythmias and conduction defects. With its help, unnecessary pacemaker implantations may be avoided. For example, symptoms
