[Role of electric stimulation in apnea syndromes].
The sleep apnoea syndrome is the best known apnoeic syndrome. It is observed in 4% of men and 2% of women. Nasal ventilation with continuous positive pressure is the best treatment for most patients. To date, electrical stimulation has a limited role in its treatment as it is used only when the apnoea requires ventilation by tracheotomy. This electrogenic ventilation requires so-called diaphragmatic stimulators. Although severe bradycardia may occur during sleep apnoea, there is usually no indication for cardiac pacing. However, recent publications have reported an anti-apnoeic effect of permanent atrial pacing. The modes of action remain unclear but these results support other recently reported data concerning the value of pacing in cardiac failure, the high incidence of sleep apnoea in cardiac failure patients and the possibility of diagnosing and monitoring apnoea by minute ventilation sensors. Therefore, there appears to be a field of research for cardiac pacing in apnoea syndromes. The authors review the principal reported data on the indications and possibilities of extra-cardiac and cardiac stimulation in apnoeic syndromes.
