No I dont think you need to worry. If you had the fluttering while the Holter was on and all they saw was sinus arrhythmia
it does not sound as though you have a worrying heart rhythm problem. I suspect you have sinus tachycardia
which can be uncomfortable but does not indicate heart disease
. It may be stess related but not always. It is normal to see air in the stomach on abdominal X ray and I imagine this is what they were referring to. If you did not have the fluttering during the Holter ask your Cardiologist if you need a longer period of monitoring or a pateint activated monitor. Also you may wish to ask if a beta blocker
tablet might help. If you do have stress
, natural stress remedies eg relaxation exercises are better than medication!
