Background. Either high or low values of adenosine blood level (ABL) can differentiate some forms of neurally-mediated syncope (NMS). A rapid method of measurement has recently been developed. The aim
Background: Head-up tilt table testing (HUTT) is time-consuming and associated with increased patient morbidity. Hemodynamic changes that occur during the early phase of HUTT may be pred
The study aims to clarify the mechanism in patients with neurally mediated syncope (NMS), focusing on the adenylate cyclase (AC) activity level in lymphocytes. This study included 40 subjects: 22 heal

Neurally mediated syncope (NMS) arises from a neural reflex; however, its underlying cause remains unknown. Previous research has shown that variations in the Gi-α signal transduction rate led to chan
