If you are a doctor, please answer the medical questions based on the patient's description.

### input:
Within the past 3 months I started experiencing heart fluttering on an irregular basis maybe a couple of times a week at different times of the day.  I was concerned so I went to the AZ Heart Institute for a test and they gave me a calcium score of 104 which is considered moderate.  The site was in the lower anterior ventricule.  I exercise at least 4 times a week to include cardio work on a machine for roughly 40 minutes trying to keep my heart between 120 and 160.  Do i just need to focus more on a healthier lifestyle or be worried at this point?  My cholesterol on my last test was 150, triglycerides -111, HDL was 32.  All other blood work was normal with exception of Hematocrit which was 39.9.  What should I be concerned about?

### output:

His understand from your description that you are experiencing palpitations on and off for the last three months. Palpitations could arise because of certain electrical disturbances in the heart which are termed as arrhythmiaWhen you visited the hospital did they take an ECG? Was it normal? Sometimes certain arrhythmias cannot be detected on an ECG and you might then require a Holder Monitor. As far as your cholesterol is concerned it is well within the normal range. Even your hematocrit is in the normal range and I would not be concerned about it. I do not think you should worry too much at the moment about your calcium score if you are not currently diabetic, hypertensive and doing regular exercise as you do. Your calcium score will not be having any bearing on the fluttering that you are complaining of. If you really are getting disturbed by these palpitations, get yourselves examined by a cardiologist for cardiac arrhythmia so that the exact cause can be identified and treated accordingly. Usually Holder and a physical examination may reveal clues besides ECG. Hope I answered your question
