Postural Orthostatic Tachycardia Syndrome (POTS): Symptoms, Causes, Types & Diagnosis

Image
(POTS) is a complex disorder that affects blood circulation and the autonomic nervous system. People with POTS syndrome experience a rapid increase in heart rate when moving from sitting or lying down to standing, often leading to dizziness, fatigue, and even fainting. This condition can significantly impact daily life, but with proper diagnosis and guidance from POTS specialists , patients can manage symptoms effectively and improve their quality of life. What is Postural Orthostatic Tachycardia Syndrome? Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia—a disorder of the autonomic nervous system. The autonomic system controls involuntary functions such as heart rate, blood pressure, and digestion. When someone stands up, the body should adjust blood flow automatically. However, in POTS syndrome , this adjustment fails, causing the heart rate to spike by 30+ beats per minute (or exceed 120 bpm), leading to uncomfortable and sometimes disabling symptoms. Be...

Tilt Table Test: Purpose, Procedure, and What to Expect

Image
  The tilt table test is a diagnostic procedure used to evaluate autonomic nervous system disorders , including Postural Orthostatic Tachycardia Syndrome (POTS) , syncope (fainting) , and orthostatic hypotension . By simulating the effects of standing in a controlled environment, this test helps doctors determine how your heart rate and blood pressure respond to positional changes. For patients experiencing dizziness, rapid heartbeat, fainting, or unexplained fatigue, the tilt table test provides critical insights into cardiovascular and autonomic function . What is a Tilt Table Test? A tilt table test involves lying on a motorized table that can move from a horizontal to a vertical position while monitoring heart rate, blood pressure, and sometimes blood oxygen levels. The goal is to observe how your body reacts to changes in posture and identify abnormal cardiovascular or autonomic responses. This test is especially valuable for diagnosing conditions like: POTS (Postu...
