The role of α7 nicotinic acetylcholine receptor in modulation of heart rate dynamics in endotoxemic rats. [PDF]

PLoS ONE, 2013
Previous reports have indicated that artificial stimulation of the vagus nerve reduces systemic inflammation in experimental models of sepsis. This phenomenon is a part of a broader cholinergic anti-inflammatory pathway which activates the vagus nerve to

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
