I fainted or nearly fainted: which doctor should I see?

What many people think

Many people see a neurologist first.

Why it may be related to the heart

Fainting can come from the heart, due to a rhythm or blood pressure problem. That is why a cardiologist should also evaluate it.

When to see a cardiologist

Any time you have fainted, especially during effort, while lying down, after palpitations, or if relatives died suddenly.

Tests usually ordered

  • Electrocardiogram (ECG)
  • 24-hour Holter
  • Echocardiogram

24-hour Holter at home

Frequently asked questions

It happened once and I feel fine. Should I still go?

Yes. Even if you feel fine, fainting deserves a check-up to find the cause.
