I've been having occasional palpitations and a strange but mild sensation in my chest (not pain). When I check my pulse during one of these, I cannot detect an irregular rhythm. It seems like my heart is beating with evenly-spaced beats. Some of the beats may be harder than others, but everything seems regular. My pulse rate from a pulse oximeter seems normal and my BP seems normal.

For some reason though I can't shake the sensation that my heart is fluttering. Would I be able to detect this by checking my pulse?
