Parahissian Cardiac Stimulation – New Alternative for More Physiological Stimulation of the Heart?

Since the implantation of the first cardiac pacemaker in 1958, artificial cardiac pacing has been the subject of innumerable research, great technical improvement, and technological innovations. Thus, the correction of bradyarrhythmias using implantable electronic devices is the area in which one of the greatest advances in knowledge within Interventional Cardiology has been observed.

More recently, the description of a new technique, the so-called physiological cardiac stimulation, caused great enthusiasm among specialists and a real transformation in the evolution of patients. Physiological stimulation includes a set of methods intended to electrically stimulate, directly or indirectly, the intraventricular conduction system of the heart. Its great benefit is to minimize the deleterious effects caused by direct stimulation of the right ventricular myocardium (RV), which generates dyssynchrony and possible left ventricular contractile dysfunction in the medium and long term. ^,
