possible arrhythmia

hello, ive been getting skipped beats for the past three months, ive had an ecg and worn 48 hr holter monitor, which have picked them and ruled as benign, my resting pulse is normal at about 70 beats per second, however i can always feel it thumping when i move around, i get about one hundred per day and taking 25mg of atenolol which doesn't seem to be helping, today ive been getting skipped beats about three or four in a row,, beat skip beat skip beat skip beat skip beat and the palitations are getting worse on a daily basis, is it possible that i have some form of arrhythmia that may not be serious and not necesarrily require medication, that my doctor is not telling me about to prevent me from worrying and if so what type could it be even if it is minor?... thanks

I'm also new to these PAC's. Been having them for about 6 months now on and off. From what I've read all we can do is trust in our Dr's best judgement and live the healthiest lifestyle we can. I too am wondering if this is something I'll have to deal with the rest of my life or if it will one day just go away:)
