The best method for cardiac pacing is transvenous. The percutaneous transfemoral approach has gained increasing popularity, especially when the objective is to obtain a His‐bundle recording. Although most of the clinical experience on cardiac pacing in the past decade has been with ventricular pacemakers, atrial pacing is becoming an increasingly important clinical tool. Among its many diagnostic, prognostic and therapeutic applications are: stress test for angina, diagnosis of the Wolff‐Parkinson‐White syndrome, recognition of bilateral bundle‐branch block, differentiation between mitral valvular obstruction and left ventricular dysfunction in rheumatic heart disease, selection of the pacing site in the sick sinus syndrome, and safe termination of supraventricular tachycardias in overdigitalized patients. The extensive use of cardiac pacemakers has also resulted in a new spectrum of auscultatory phenomena. Their occurrence depends upon the mode and site of pacing, the nature of the supraventricular rhythm, and the production of extra sounds and murmurs by the pacing catheters. An understanding of these phenomena is useful for proper clinical evaluation of pacemaker function as well as the underlying cardiac dysrhythmias.
