To test for POTS at home, measure your heart rate and blood pressure while lying down. Then, stand up and immediately take your measurements again. A heart rate increase of 30 beats per minute or more within 10 minutes of standing suggests POTS. Report these findings to your healthcare provider for further evaluation.
What is Postural Orthostatic Tachycardia Syndrome (POTS)?
Picture this: you stand up from a relaxing seat, anticipating a productive day ahead. But instead of feeling refreshed, you’re hit with a wave of dizziness and your heart pounds like a drum in your chest. Welcome to the enigmatic world of Postural Orthostatic Tachycardia Syndrome (POTS).
POTS is a complex disorder that affects the way your body responds to standing up. When you rise from a reclined position, your sympathetic nervous system (the body’s fight-or-flight response) kicks into gear. This surge of adrenaline helps to increase your blood pressure and heart rate, enabling you to maintain an upright posture.
However, in individuals with POTS, this response is exaggerated. Upon standing, their heart rate increases by an abnormal amount (usually more than 30 beats per minute). This rapid heart rate causes symptoms such as lightheadedness, fatigue, brain fog, and chest pain.
Symptoms of Postural Orthostatic Tachycardia Syndrome (POTS)
Postural Orthostatic Tachycardia Syndrome (POTS) manifests through a constellation of symptoms that can significantly impact daily life. At the core of POTS is lightheadedness and dizziness upon standing, triggered by an abnormal increase in heart rate. This can be accompanied by a range of additional symptoms that vary in severity and manifestation:
-
Lightheadedness and Dizziness: POTS is characterized by a persistent sensation of lightheadedness or dizziness, especially upon standing or when transitioning from sitting to standing. This is due to a drop in blood pressure upon standing, causing inadequate blood flow to the brain.
-
Fatigue: Unexplained fatigue is a common complaint among POTS patients. This fatigue can be debilitating, interfering with daily activities and making even simple tasks seem overwhelming.
-
Brain Fog: Difficulty concentrating, poor memory, and an overall “foggy” feeling in the head are all symptoms of POTS. They can significantly impair cognitive function and make it challenging to focus or learn new information.
-
Chest Pain: POTS can cause chest pain or discomfort, which can be mistaken for heart problems. This pain is typically related to the autonomic dysfunction that underlies POTS.
-
Other Symptoms: POTS can also cause a wide range of other symptoms, including:
- Palpitations
- Shortness of breath
- Headaches
- Nausea
- Abdominal pain
- Temperature intolerance
- Visual disturbances
Diagnosis of Postural Orthostatic Tachycardia Syndrome (POTS)
Understanding how POTS is diagnosed is crucial for proper treatment and management. The journey to a POTS diagnosis involves several tests that assess your blood pressure, heart rate, and autonomic nervous system function. Here’s a closer look at these tests:
-
Blood Pressure and Heart Rate Measurements:
Your doctor will measure your blood pressure and heart rate while you’re lying down and then again after you stand up for a few minutes. If your blood pressure drops significantly or your heart rate increases significantly upon standing, it may indicate POTS.
-
Tilt Table Test:
This non-invasive test simulates standing for a prolonged period. You’ll be strapped to a table that’s tilted upright while your blood pressure, heart rate, and symptoms are monitored. If you experience lightheadedness, fainting, or a significant increase in heart rate during the test, it further supports a POTS diagnosis.
-
Autonomic Testing:
This comprehensive test evaluates the function of your autonomic nervous system, which regulates involuntary bodily functions like blood pressure, heart rate, and digestion. The test may include:
- Quantitative Sudomotor Axon Reflex Test (QSART): Assesses sweat gland function by stimulating the skin with a small electrical current.
- Thermoregulatory Sweat Test (TST): Measures sweating responses to changes in body temperature.
- Heart Rate Variability (HRV): Records the variation in your heart rate over time, providing insights into autonomic nervous system balance.
Treatment Options for Postural Orthostatic Tachycardia Syndrome (POTS)
Managing POTS can be a journey, but with the right treatment, people with this condition can improve their symptoms and live fulfilling lives. Here are some effective treatment approaches:
Fluid Intake:
- Staying well-hydrated is crucial for people with POTS. Increased fluid intake helps maintain blood volume, reducing the risk of lightheadedness and rapid heart rate upon standing. Aim for 6-8 glasses of water or electrolyte-rich beverages daily.
Gradual Exercise:
- Exercise may seem counterintuitive for those with POTS, but gradually increasing activity can improve symptoms. Start with low-intensity exercises like walking or swimming and slowly increase the duration and intensity as tolerated. Exercise helps strengthen the cardiovascular system, improving blood flow and reducing symptoms.
Medications:
- Certain medications can help manage symptoms of POTS. These may include:
- Beta-blockers: Slow down the heart rate
- Midodrine: A vasoconstrictor that helps increase blood pressure
- Fludrocortisone: Retains fluid, increasing blood volume
- Pyridostigmine: Helps improve nerve function
Compression Garments:
- Compression stockings or abdominal binders can help support blood flow and reduce pooling in the lower extremities. Wearing compression garments during activities like standing or exercising can improve symptoms.
Lifestyle Modifications:
- Lifestyle changes can significantly impact POTS symptoms. Here are some recommendations:
- Avoid prolonged standing: Take frequent breaks to sit or lie down
- Elevate legs: When sitting or lying down, try to elevate your legs to promote blood flow
- Consume salty foods: Sodium intake helps retain fluid and increase blood volume
- Manage stress: Stress can exacerbate POTS symptoms. Techniques like meditation or yoga can help manage stress levels
- Get enough sleep: Sleep deprivation can worsen symptoms. Aim for 7-9 hours of restful sleep each night
Postural Orthostatic Tachycardia Syndrome (POTS): A Guide to Understanding and Managing Your Condition
Understanding POTS
Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the body’s ability to regulate blood pressure and heart rate upon standing. It causes a rapid increase in heart rate (tachycardia) and lightheadedness or dizziness when you stand up. This can impact daily life, causing a range of symptoms beyond lightheadedness.
Common Symptoms of POTS
Along with dizziness and lightheadedness, other common POTS symptoms include:
- Fatigue
- Brain fog
- Chest pain
- Palpitations
- Shortness of breath
- Anxiety
Diagnosing POTS
Your doctor may use various tests to diagnose POTS, including:
- Blood pressure and heart rate measurements: Performed while you are lying down and after standing for a period.
- Tilt table test: Involves lying down on a table that is tilted upright to simulate standing.
- Autonomic testing: Assesses the function of your autonomic nervous system, which controls heart rate and blood pressure.
Treatment Options for POTS
Managing POTS involves a combination of therapies:

Related Concepts
When discussing Postural Orthostatic Tachycardia Syndrome (POTS), it’s essential to grasp several related physiological concepts that provide a deeper understanding of this intriguing condition.
Orthostatic Blood Pressure
Orthostatic blood pressure refers to the measurement of blood pressure when a person transitions from lying down to standing upright. In individuals with POTS, blood pressure may drop when they stand, leading to symptoms such as lightheadedness and dizziness.
Vasoconstriction
Vasoconstriction refers to the narrowing of blood vessels, causing an increase in blood pressure. In individuals with POTS, vasosconstriction may be impaired, leading to a drop in blood pressure upon standing.
Sympathetic Nervous System
The sympathetic nervous system is responsible for the body’s “fight or flight” response. In POTS, the sympathetic nervous system may be overactive, resulting in an increased heart rate and blood pressure when standing.
Autonomic Dysfunction
POTS is primarily characterized by autonomic dysfunction, which refers to an impairment in the body’s automatic functions, such as heart rate regulation and blood pressure control. This dysfunction can lead to the various symptoms associated with POTS, including lightheadedness, fatigue, and difficulty concentrating.
