Efectos de la estimulación cardiaca convencional. Estimulación en sitios alternativos

This article discusses the possibility of using alternative atrial pacing sites, with the fundamental aim of preventing atrial arrhythmia. In addition, it also contains a detailed review of the evidence published to date on the hemodynamic and functional effects of right ventricular outflow tract pacing, its influence on the QRS duration, and its correlation with ventricular function. Finally, there is a discussion of permanent His bundle pacing, and the possible advantages associated with ventricular activation via this particular conduction system.
