If you are having persistent symptoms. Get Holter monitor done

Hello the symptoms appears like related to anxiety . Since you don’t have other symptoms like giddiness dizziness loss of consciousness and fall nothing serious . But to convince yourself that everything is fine I recommend Holter monitoring for you which records any event or arrhythmia if it’s occurring. Try to ignore and stop worrying. After Holter report contact cardiologist

Please consult..

Transient symptoms may be due to a missed beat. It may be an innocuous finding in many. A clinical consultation and review with further testing is a way forward

Holter would be advisable , but need to see your ecg first

Its all because of anxiety, no need to worry You can share the ecg for confirmation
