Postural Orthostatic Tachycardia Syndrome

What is POTS?

Postural Orthostatic Tachycardia Syndrome (POTS) is a condition characterized by an abnormal increase in heart rate when moving from lying down to standing up. This excessive heart rate increase often leads to symptoms such as lightheadedness, fainting, fatigue, and palpitations.

Symptoms

Common symptoms of POTS include:

• Rapid heartbeat (tachycardia)
• Lightheadedness or dizziness, especially when standing up
• Fainting or near-fainting (syncope)
• Fatigue
• Weakness
• Palpitations or irregular heartbeat
• Brain fog or difficulty concentrating
• Headaches
• Sweating excessively
• Nausea
• Abdominal pain
• Exercise intolerance

Causes

The exact cause of POTS is not always clear, but several factors may contribute to its development, including:

• Dysfunction in the autonomic nervous system
• Low blood volume
• Abnormalities in blood vessel regulation
• Genetic predisposition
• Trauma or infection
• Hormonal imbalances
• Autoimmune diseases

Diagnosis

Diagnosing POTS typically involves:

• Medical history review
• Physical examination
• Tilt table test: Measures heart rate and blood pressure changes in response to changes in body position
• Autonomic function tests: Assess how the autonomic nervous system regulates heart rate, blood pressure, and sweating
• Blood tests: To rule out other conditions
• Electrocardiogram (ECG or EKG): To evaluate heart rhythm and function

Treatment Options

Treatment for POTS aims to relieve symptoms and improve quality of life. Treatment options may include:

• Lifestyle modifications such as increasing fluid and salt intake, wearing compression stockings, and avoiding triggers like hot environments or prolonged standing
• Medications to regulate heart rate and blood pressure, such as beta-blockers, fludrocortisone, or midodrine
• Physical therapy to improve blood flow and muscle tone
• Exercise training programs tailored to individual needs
• Dietary changes to maintain blood sugar levels and prevent dehydration

Lifestyle Management

Managing POTS involves adopting a lifestyle that helps control symptoms and improve overall well-being, including:

• Staying hydrated by drinking plenty of fluids
• Consuming an adequate amount of salt
• Eating small, frequent meals to prevent blood sugar fluctuations
• Avoiding triggers such as hot environments, prolonged standing, or large meals
• Gradually increasing physical activity under medical supervision
• Using support devices such as compression garments or mobility aids as needed
