Need results: Since you've been to the er, surely blood work and heart rhythm were checked. You need followup. Call the doctor's office you've been waiting on. Ask for referral to a cardiologist. If you smoke or drink coffee/cola with caffeine: stop! many rhythms could cause your symptoms. Treatments differ by rhythm. Depending on your age and risk factors, the rhythm could be the tip of the iceberg.

Arrhythmia: You may have an arrhythmia. Need to see a cardiologist and have an event monitor to monitor your heart rhythm and symptoms.
