Resumo
- Neurally mediated reflex syncope (NMRS) refers to a group of related conditions or scenarios in which symptomatic hypotension occurs as a result of neural reflex vasodilation and/or bradycardia.
- Vasovagal syncope (VS) refers to a particular type of NMRS also known as the common faint.
- VS has many manifestations and is generally considered to encompass faints triggered by emotional upset, fear, and pain, as well as those occurring in less well-defined circumstances.
- Patient education is the foundation of treatment for most NMRS syndromes, including VS.
- Patients must be informed that, although reflex faints are almost never life-threatening, they tend to recur (often in clusters), and injury can result if preventive measures are not taken seriously.
- Strategies for reducing syncope recurrences in the long term comprise 1) physical techniques to improve orthostatic tolerance, 2) pharmacological interventions to prevent depletion of intravascular volume and/or enhance arterial and venous tone, 3) cardiac pacing to avert bradycardia.
