When to see a cardiologist
See a cardiologist if you have chest pain or pressure, shortness of breath with exertion, heart palpitations or irregular heartbeat, a family history of early heart disease, high blood pressure that is hard to control, high cholesterol not responding to lifestyle changes, dizziness or fainting episodes, or if your PCP detects a heart murmur or abnormal EKG.

Common reasons to see a cardiologist in Orange County, CA
Air quality in inland OC (Anaheim, Orange, Fullerton) can be worse than coastal cities due to the Santa Ana wind corridor. Seasonal allergies are common year-round due to diverse ornamental landscaping.
Chest pain evaluation
Chest pain has many causes, from muscle strain to heart disease. A cardiologist performs the testing needed to determine whether your heart is the source and develops a treatment plan if it is.
Heart arrhythmia
A heart that beats too fast, too slow, or irregularly may need treatment. Cardiologists use EKGs, Holter monitors, and other tools to diagnose the rhythm problem and determine the best approach.
Heart failure management
Heart failure does not mean the heart has stopped. It means it is not pumping as efficiently as it should. Cardiologists manage this condition with medications, lifestyle changes, and monitoring to keep you stable.
High blood pressure management
When blood pressure is resistant to standard treatment or is causing organ damage, a cardiologist provides advanced evaluation and treatment strategies beyond what primary care typically offers.
After a heart attack or heart surgery
Recovering from a cardiac event requires close monitoring, medication optimization, and cardiac rehabilitation. Your cardiologist guides the recovery process and works to prevent future events.
