Dizziness
Also known as: Lightheadedness, Unsteadiness or Vertigo
Dizziness that arises due to cardiovascular issues, can be caused by various factors affecting blood flow to the brain, such as low blood pressure, heart rhythm disturbances, reduced cardiac output, or structural heart abnormalities.
What are the symptoms of Dizziness?
Symptoms of dizziness in cardiology may include:
Light-headedness or feeling faint
Vertigo, a spinning sensation
Nausea or vomiting
Feeling off-balance or unsteady
Blurred vision or difficulty focusing
How is Dizziness diagnosed?
Diagnosis of dizziness in cardiology involves:
Comprehensive medical history assessment, focusing on cardiovascular conditions and risk factors.
Physical examination to assess heart function and rhythm.
Diagnostic tests such as electrocardiogram (ECG), echocardiogram, Holter monitor, stress test, or tilt table test to evaluate heart function, rhythm, and blood flow.
Electrocardiogram (ECG/EKG):
This test records the electrical activity of the heart and may detect abnormalities in heart rhythm or conduction.
Holter Monitor or Event Monitor:
These portable devices record heart rhythm continuously or intermittently over a period to capture any abnormal heart rhythms that may cause Syncope.
Echocardiogram:
This ultrasound test evaluates the structure and function of the heart and may detect structural abnormalities or conditions that increase the risk of Syncope.
Tilt Table Test:
This specialised test assesses cardiovascular responses to changes in body position and may help diagnose vasovagal Syncope or autonomic nervous system dysfunction.
How is Dizziness treated?
Treatment for dizziness in cardiology depends on the underlying cause:
Lifestyle changes:
Such as maintaining hydration, avoiding triggers (caffeine, alcohol), and improving circulation.
Medications:
Managing associated cardiovascular conditions with medication or interventions.
Procedures
Procedures or surgeries to address structural heart issues if necessary.
Vestibular Rehabilitation Therapy
Vestibular rehabilitation therapy may be recommended for certain cases of Vertigo.
