Most of the day yesterday I had fluttering in my chest.  Ive had this before but not for such a long period of time.  Ive been noticing some tingling in my hands recently also.  I am 50 and my mom has heart issues.  I was sitting most of the day and not anxious about anything.
One episode isn't cause for alarm. Keep to regular, healthy lifestyle activity like daily exercise and pursue the sensation only if it is recurrent.
