Paroxysmal Sympathetic Hypertension: An Underdiagnosed Entity or a Diagnostic Difficulty?

Area of Science:

• Critical Care Medicine
• Cardiology
• Neurology

Background:

• Paroxysmal sympathetic hypertension (PSH) is characterized by sudden, severe elevations in blood pressure.
• It is often associated with specific neurological conditions or injuries.
• PSH can be mistaken for other hypertensive emergencies, complicating diagnosis and treatment.

Purpose of the Study:

• To highlight the diagnostic challenges associated with paroxysmal sympathetic hypertension.
• To review the clinical presentation and underlying causes of PSH.
• To discuss current understanding and potential management strategies for PSH in critical care.

Main Methods:

• Literature review of studies on paroxysmal sympathetic hypertension.
• Analysis of case reports and clinical series.
• Synthesis of information on diagnosis, triggers, and management.

Main Results:

• PSH is frequently underdiagnosed due to its episodic nature and overlap with other conditions.
• Specific triggers, such as autonomic dysfunction or brain injury, are often identified.
• Prompt recognition and targeted management are crucial for preventing severe complications.

Conclusions:

• Paroxysmal sympathetic hypertension represents a significant diagnostic hurdle in critical care.
• Increased awareness and standardized diagnostic approaches are needed.
• Effective management requires addressing the underlying cause and controlling hypertensive episodes.
