This Short Editorial is referred by the Research article "Left Bundle Branch Pacing of His-Purkinje Conduction System: Initial Experience".
Yes, the old dream, the stimulation of the His-Purkinje system, has become reality and is now replacing the conventional pacing. In this sense, the article “Stimulation of the Left Branch of the His-Purkinje System: Initial Experience” is a great step and should be read not only by the stimulist, but also by the general cardiologist and by the electrophysiologist.1
In the 60s and 70s, the main purpose of the pacemaker was to correct the heart rate in Stokes-Adams syndrome with total AV block. Pacemakers were dependent on epicardial leads, implanted by thoracotomy. However, in 1959 Furman introduced the endocardial pacing,2 without thoracotomy, becoming the standard of modern cardiac pacing in the right ventricular apex. The success of the cardiac stimulation was extraordinary. Nevertheless, an important limitation emerged due to the lack of atrioventricular synchronism given origin to a first problem: The “Pacemaker Syndrome”,3 whose prevention gave rise to the atrioventricular pacemaker.
