Double Beat, Triple Beat

Until 12 months ago I was in sinus at 50 bpm. Since then my heart has gradually inserted double beats and triple beats in place of a single heartbeat. Occasionally there will be four beats where there should only be one beat. I do not feel these multiple beats and they cause no discomfort. At this time they have become continuous all day, all night. I am now rarely in sinus. Is this a benign condition or is this dangerous? I get out of breath walking up small slopes. I have had 2 ablations which cured me of afib and aflutter.

I don't have enough information to comment on if it is dangerous.
It would depend on lots of other data like: heart function, EKG, heart disease or no heart disease (coronary disease).

I am concerned about the symptoms of shortness of breath, but again, there is a lot of information necessary to determine the cause of shortness of breath and if it could be cardiac.  It is important to discuss these symptoms with your doctor and ask them that direct questions about whether the arrhythmia is dangerous.
