چکیده انگلیسی
Neuroendocrine syncope is a newly proposed term to embody both syncope of reflex and adenosine-related etiology. Recent publications on tilt testing have revealed the presence of a hypotensive tendency in some patients, even in the face of severe cardioinhibition. This new understanding may allow better selection of older reflex syncope patients, documented by ECG loop recorder, for successful pacing where tilt testing is ideally negative for a good result in terms of few syncope recurrences and prompts a less aggressive management policy when hypotensive medication is required. Furthermore, plasma adenosine levels not only define a new group of patients who have low adenosine and will respond well to cardiac pacing but also, by assessing adenosine receptor affinity, offer a possible explanation for vasodepression accompanying severe cardioinhibition. The question of the timing of loss of consciousness in reflex syncope needs to be addressed because, if consciousness is lost before asystole, pacing is likely to be ineffective.
