About Dizziness & Fainting
Dizziness and fainting (syncope) can be caused by heart rhythm disorders, structural heart problems, or changes in blood pressure. While many causes are benign, such as vasovagal syncope (a simple faint triggered by standing too long or stress), cardiac-related fainting can be a warning sign of a serious underlying condition that needs urgent assessment. Cardiac causes include arrhythmias (abnormal heart rhythms), aortic stenosis, hypertrophic cardiomyopathy, and bradycardia (slow heart rate). Fainting during exercise is always a red flag and should be investigated promptly by a cardiologist.
Common Symptoms
- Feeling light-headed or faint
- Sudden loss of consciousness (fainting)
- Dizziness with standing or exertion
- Near-fainting episodes (pre-syncope)
- Blackouts or unexplained falls
- Fainting during or after exercise
When to See a Cardiologist
If you have experienced fainting, recurrent dizziness, or blackouts, particularly during exercise or without warning, a cardiologist should assess whether a heart condition is the cause. Fainting that occurs during physical activity, while seated, or without any prodromal symptoms (warning signs) is considered high-risk and requires urgent investigation.
How We Investigate
A 24 Hour Holter Monitor records your heart rhythm continuously to detect arrhythmias that may cause dizziness or fainting. An echocardiogram can identify structural problems such as valve disease, cardiomyopathy, or reduced pumping function that may be responsible for syncope.
