Heart arrhythmia...possibly stress related?

Hi all,,

i consider that i am a healthy male,dont smoke ,only drink a couple of glasses of wine a week,close to ideal BMI, reasonable exercise etc,

Recently i have noticed periods where maybe im sitting still and suddenly i will get a series of fluttering type sensations in the left of my chest that feel like they are above my heart rather than actually from within it. Sometimes i automatically cough.
After a short while the feelings subside and everything returns to normal.

I regularly measure my resting BP and it is typically around the "ideal" 120/80 6o bpm though sometimes the systolic is elevated at maybe 130/138 and diastolic can be toward 70.

I know it can vary for assorted reasons.

Having googled it seems i might be suffering PAC/PVC

Does this sound familiar to anyone?

thanks

Hi Sean..Thanks for the reply..

No i dont think there are any associations. I just drink tea at a normal rate,no coffee,no stimulant drinks,no prescription or err..other drugs.no real dietary changes etc.. the only thing i can think of is an additional dollop of stress and subsequent re-adjustments over maybe a few months..average bp reads over last few weeks are 125/73 62 bpm MAP 91
