cardiac or autonomic issues
for dizziness that comes with palpitations, heart rhythm concerns, blood pressure swings, or near-fainting.
pattern snapshot
how this pattern tends to show up
this pattern leans more circulatory than vestibular, especially when palpitations or near-fainting show up too.
common trigger
standing, exertion, heat, dehydration, stress
how it feels
fluttering, racing heart, weak, or near-fainting
timing clue
matches posture, exertion, or heart rhythm changes
what is it
simple breakdown
Some dizziness is less about the inner ear and more about circulation, heart rhythm, or autonomic regulation. That can overlap with orthostatic symptoms, especially if heart rate and blood pressure shift a lot with posture.

finding the right kind of help
If this pattern sounds familiar, bring heart rate, blood pressure, trigger, and timing details to a clinician instead of assuming it is only vestibular.
clinicians who may help
depending on the pattern, that may include an autonomic neurologist, cardiologist, electrophysiologist, primary care physician, physical therapist, rheumatologist, nutrition professional, or psychotherapist familiar with chronic autonomic illness.
the right specialty matters
autonomic and POTS-type symptoms can look overwhelming, so it helps to find someone who already understands orthostatic vitals, heart-rate and blood-pressure changes, and gradual rehab rather than starting from scratch with a general clinic.
The Dysautonomia Project's find a clinician tool is a good place to start. it can also help to ask your PCP or cardiologist for referrals, connect with support groups, and check organizations like Dysautonomia International for POTS-aware clinicians.
