↓  Table 1. The Definition, Types, Clinical Features, and Potential Complications of Vasovagal Syncope (VVS)
 
Aspect Details Reference
Definition VVS is characterized by a sudden decrease in heart rate (HR) and/or blood pressure (BP), often triggered by stress during pain management procedures. [5]
Types of VVS Cardioinhibitory: HR < 40 beats per minute (bpm); vasodepressor: systolic BP < 80 mm Hg or a decrease of > 30% without significant HR reduction; mixed: HR < 40 bpm and systolic BP < 80 mm Hg or a decrease of >30%. [6]
Symptoms Light-headedness, palpitations, weakness, blurred vision, nausea, warmth/coldness, sweating. [7]
Severe manifestation If a VVS leads to loss of consciousness, it is termed vasovagal syncope. [7]
Clinical impact Generally benign but can cause serious complications such as discontinued procedures; cardiac arrhythmias, and fear of planned procedures (for patients and providers) [7]
