ER: With your history of angina, previous cath, it is best to assume your symptoms are cardiac until proven otherwise.

Irregular heart beat: It sounds like you are experiencing symptomatic palpitations, and you need to be evaluated. You should have an ekg done, also a heart ultrasound (echocardiogram) to assess your overall heart function and valves, and you may need to wear a holter monitor for 24 hours to look for abnormal heartbeats. These tests check the heart's structure and electrical system, either can cause your symptoms.
