Hi,
Heart flutter may be due to cardiac causes, thyroid disorders, digitalis toxicity, hypoglycemia, anxiety disorders, hypertension, drug allergies and a lot more. Are there other symptoms present? A complete medical history and physical examination is important to help with the diagnosis. Some diagnostic modalities such as ECG may be done to rule out other causes.Having a family history of heart problems already increases your risk. I would recommend that you have this evaluated further by your doctor.
Take care and regards.
