Seen my heart dr yesterday. after exam he said he thinks my heart flutter is benign but ordered test to be sure. should i worry, 31 healthy.

Abnormal: Flutter is always abnormal. Now it might be "rate controlled" or compensated. Regardless i think he might have spoken to you about about being on medications, of-course a full work up , a close follow up strategy and also a referral to a cardiologist for expert management.

Listen to MD: Sounds like your doctor is on the right track. Don't be worried and follow his suggestions
