You really need the cardio telemetry used from the pacemaker to determine what your burden is. Burden is based on how many heart beats and how many PVC events over a period of time. So you cannot have some here suggest that your burden is "0.2% burden" based on guessing 72 BPM and also guessing how long the PVC is. That is not acceptable to just guess someone's HR and determine their burden. There is a big difference between 2% burden and 0.2% burden. A simple way to present this is 20 cents is 20% of a 100 cents. Which makes 2 dimes 20%= 0.2 X 100.I didn't finish. So .2% of 20%(20 dimes) would = 4 cents. So the example given to you is not the methodology of describing %s correctly. It is a confusing.
My recent monitor for 30 days had my burden @ 21% with a HR of 50 BPM. So that is scary high burden. Fortunately my heart has reset itself and the the burden has dropped dramatically. I am now using a Kardia mobile device checking it regularly. I can also feel the difference. My energy is so much better and I feel so much better. This results in better perfusion. Real high sustained burden ratio of PVCs and or PACs decreases perfusion and increases stress to the heart much like Afib can also do. Also I would be careful about listening to contributors here predicating that this will get worse as you "age and acquire a condition or two that encourages the progression." That is really not true and if it is then let your cardio doc be the one to determine what you might be faced with in the future.
