Pathophysiology of reflex syncope: A review.

Area of Science:

• Cardiology
• Neurology

Background:

• Reflex syncope encompasses several conditions including vasovagal syncope, carotid sinus syndrome, and situational syncope.
• Understanding the underlying pathophysiology is crucial for accurate diagnosis and management.

Purpose of the Study:

• To review the pathophysiology of reflex syncope.
• To clarify the nomenclature associated with different types of reflex syncope.

Main Methods:

• Literature review of existing studies on reflex syncope.
• Analysis of pathophysiological mechanisms.
• Examination of current terminology and classification.

Main Results:

• Detailed explanation of the neuroautonomic mechanisms involved in reflex syncope.
• Distinction between vasovagal syncope, carotid sinus syndrome, and situational syncope based on triggers and pathways.
• Recommendations for standardized nomenclature.

Conclusions:

• Accurate understanding of reflex syncope pathophysiology supports precise diagnosis.
• Standardized nomenclature improves communication and research in syncope management.
