Heart Palpitations: When Your Heart Races and Doctors Say 'It's Anxiety'

The short answer

Heart Palpitations: When Your Heart Races and Doctors Say 'It's Anxiety'

Heart palpitations are terrifying — and dismissing them as 'just anxiety' misses potentially treatable root causes.

Heart Palpitations Are Not "Just Anxiety"

Racing heart, skipped beats, pounding chest — while anxiety can cause these, stopping there means missing treatable conditions.

Root Causes to Investigate

  • Magnesium Deficiency — 75% of Americans are deficient; standard blood tests miss intracellular deficiency
  • Thyroid Dysfunction — complete thyroid panel is essential
  • Histamine Intolerance — excess histamine directly stimulates heart rate
  • Dysautonomia / POTS — inappropriate heart rate responses
  • Electrolyte Imbalance — potassium, calcium, sodium
  • Stimulant Sensitivity — caffeine, medications, supplements
  • Mitral Valve Prolapse — common structural variant

Our Cardiac Investigation Protocol

  1. Complete electrolyte and mineral panel (including RBC magnesium)
  2. Full thyroid panel
  3. Histamine and mast cell markers
  4. Autonomic testing for dysautonomia
  5. Nutrient repletion — magnesium, potassium, CoQ10
  6. Nervous system regulation — vagus nerve exercises, meditation

We don't guess. We test.

Precision or nothing.

90% of the clarity that produces outcomes comes from a precise, investigative intake — a series of questions no one has ever asked you. Testing follows the hypothesis: epigenetic DNA in DNA Precision, doctor-selected blood and urine panels in Private Concierge. Nothing gets recommended that the data can't justify.

  • We never give up

    Complex, weird, and "nothing worked" cases are the ones we take.

  • We have your back

    You are not managing this alone between appointments.

  • We always find the root cause

    We keep going upstream until the pattern explains every symptom.

  • We look at all of you

    Mind, body, exposure history, genetics, and the life you are actually living.

  • Precision or nothing

    No shotgun protocols. If we cannot justify it, you do not take it.

  • Clarity produces outcomes

    When you understand why, implementation stops being a willpower problem.
