occasional fluttering common;ECG to rule out cardiac issues.
Detailed Answer:
Hello
Welcome to HCM.
I can understand your concerns.
Occasional fluttering is very common and is normal. Since you are not having any pain or tightening, I think this should not be worrisome. The best treatment would to try and and ignore it.
I would still suggest you to go for an ECG to be sure that there are no cardiac issues.
The other common reasons for fluttering are Stress or anxiety states: Are you facing some kind of stress in recent times?
or
Some OTC drugs like allergy medicines: Do you take any medicines?
Anemia or thyroid conditions should also be ruled out with the help of blood tests.
The treatment will depend on the cause.
If you feel pain with nausea then possibility of acid relux also there, you can take OTC antacids for that.
Hope this helps.
Thanks.
