ECG: An ECG lasts for 10 seconds. Obviously, you're having an intermittent arrhythmia that was missed on such a brief recording. You need a 24 hour (holter) exam. Additionally, blood sample for potassium, magnesium, thyroid, and kidney function should be done. Also an echocardiogram to screen for structural heart disease. Treatment depends on findings. Avoid nicotine, caffeine, and other stimulants.

Need more testing: A normal ECG does not rule out rhythm problems. Are you taking any prescription medications or over the counter cold medicines? How much caffeine do you take? Since your symptoms are intermittent i would recommend wearing a holter monitor - a 24-48 hour recording of every heart beat. A heart echo to evaluate the heart for any structural abnormalities would also be a good idea. Ask your doctor.
