[Postural orthostatic tachycardia syndrome].

Area of Science:

• Neurology
• Cardiology
• Immunology

Background:

• Postural Orthostatic Tachycardia Syndrome (POTS) is a heterogeneous condition.
• It involves dysautonomia and suspected autoimmunity.
• Characterized by abnormal heart rate increase upon standing, leading to cerebral hypoperfusion and sympathoexcitation.

Purpose of the Study:

• To summarize the diagnostic criteria and management strategies for POTS.
• To highlight the key features of this complex neurological disorder.

Main Methods:

• Diagnostic criteria based on head-up tilt test.
• Assessment of heart rate increments (≥30 bpm or >120 bpm).

Main Results:

• The primary diagnostic criterion is a significant heart rate increase during a head-up tilt test.
• Symptoms include cerebral hypoperfusion and sympathoexcitation.

Conclusions:

• POTS management requires a multifaceted approach.
• Treatment involves non-pharmacological methods like stress management and volume expansion.
• Pharmacological interventions focus on heart rate control.
