Dizziness and fainting (syncope) may signal heart rhythm or blood pressure problems.
Causes include arrhythmias, valve disease, low blood pressure, and dehydration.
Urgent if fainting occurs during exertion or with chest pain.

Introduction
Feeling lightheaded or fainting is frightening—and often dismissed as a “one-time thing.” But repeated dizziness or passing out can indicate serious heart disease. In Brampton, Mississauga, and Milton, I frequently see patients who ignored these episodes until they worsened.
Causes of Dizziness and Fainting
Heart-Related
Arrhythmias: Fast or slow heart rhythms reduce blood flow to the brain.
Valve disease: Narrowed valves reduce circulation.
Cardiomyopathy: Weak heart muscle limits oxygen delivery.
Non-Heart Related
Dehydration or low blood pressure.
Neurological conditions.
Medication side effects.
Red Flag Situations
Fainting during exertion.
Fainting with chest pain or palpitations.
Sudden collapse without warning.
