POTS vs. Anxiety
A quick-reference chart for teen girls, families, educators, and healthcare providers to tell autonomic dysfunction (POTS) apart from psychological anxiety and panic attacks.
The comparison
6 things to look at when a racing heart gets called a panic attack. The pattern of the symptoms, not the symptoms themselves, is what separates them.
| Feature | POTS (Postural Orthostatic Tachycardia Syndrome) | Anxiety or panic attack |
|---|---|---|
| Primary trigger | POTSPhysical: moving from lying or sitting to standing, or standing still for extended periods. | Anxiety or panicPsychological: stressful thoughts, sensory overload, environments, or emotional triggers. |
| Heart rate pattern | POTSSpikes by 30+ BPM (or exceeds 120 BPM) specifically upon standing; usually settles when lying flat. | Anxiety or panicSustained high heart rate regardless of physical position (sitting, standing, or lying down). |
| Positional relief | POTSImmediate and significant: symptoms improve rapidly within minutes of lying down or elevating the legs. | Anxiety or panicMinimal to none: lying down does not automatically resolve the elevated heart rate or panic. |
| Physical signs | POTSBlood pooling in legs and hands (purple or mottled skin), "coat hanger" neck and shoulder pain, cold hands and feet. | Anxiety or panicSudden facial flushing, generalized heat, sweating, tremors, or hyperventilation. |
| Recovery | POTSSymptoms usually improve significantly within minutes of lying down; hydration and salt are known to help. | Anxiety or panicSymptoms persist until the emotional stressor fades or self-soothing techniques take effect. |
| Underlying mechanism (the "why") | POTSFailure of the Autonomic Nervous System (ANS) to properly constrict blood vessels against gravity. | Anxiety or panicActivation of the body's adrenaline, or "fight-or-flight," pathway, triggered by the brain's amygdala. |
How to use this chart
In clinical appointments
When a physician suggests a postural heart rate spike is "just anxiety," use this response:
My heart rate consistently increases by over 30 beats per minute specifically when I stand up, and it drops immediately when I lie flat. Because this symptom is strictly positional and tied to postural changes rather than emotional stressors, I would like to request an evaluation or tilt-table test for postural dysautonomia.
For educators and school health personnel
When a student presents with sudden fatigue, lightheadedness, or a rapid pulse in class:
- Check position. Has the student been standing at a podium, waiting in line, or sitting motionless for an extended duration?
- Intervene. Allow the student to sit down, elevate their feet, and drink water. If symptoms improve upon sitting or lying down, this points toward positional orthostatic intolerance rather than classroom anxiety.
