Your doctor will review your medical history.
He or she will ask about:
Your family's history of heart disease
Any family members whose death was sudden and unexplained
Specific circumstances that trigger your heart-related symptoms
Your doctor will examine you, paying special attention to your heart.
This will be followed by:
An electrocardiogram (EKG). This test records the electrical activity of your heart.
A chest X-ray
An echocardiogram. This test uses sounds waves to create a picture of the heart at work.
You may also need other tests.
