Depends of course on the type of ECG abnormality. Higher heart rates and lower blood pressure often imply relative low volume in the bloodstream. Make sure you are hydrated. If you have a sense of racing heart (palpitations) and light headedness, you should see your doctor for another ECG, possible an echo or check structure and function of heart. Increased adrenergic (adrenalin) tone can occur if anxious.
