Alternative endocardial sites for artificial cardiac stimulation.

Arquivos brasileiros de cardiologia, 2011
The conventional right ventricular stimulation can be associated with deleterious effects on cardiac function. The need for a more physiological artificial cardiac stimulation is undoubtedly one of the most important points in the area of cardiac electrotherapy. The programming algorithms for the maintenance of adequate atrioventricular conduction, the
