A look through the medical reports of arrhythmia patients shows that quite a few of them describe how they had a strange "fluttering" sensation in their necks or chest. Unless you are unfortunate enough to experience this symptom if is probably going to be hard to envisage what exactly they felt.

They will certainly want to check if this might be an arrhythmia symptom or something it is safe to ignore.
