Summary
Beta blockers effectively prevent vasodepressor syncope by normalizing sympathetic dominance, indicated by the LF/HF ratio, during orthostatic stress. This treatment reduces fainting episodes and associated symptoms.
Area of Science:
- Cardiology
- Autonomic Neuroscience
Background:
- Vasodepressor syncope is a common cause of fainting.
- Orthostatic stress can reveal autonomic nervous system imbalances.
