shortness of breath relation to pacemaker

My mom is suffering from shortness of breath on with increased activity.  She is an active 85 year old.  I believe that it is related to her pacemaker.  Can that be adjusted to help this?
Thank you

Tell her to do this pranayam for 15 minutes, twice a day, and her breathing will improve gradually. Continue the pranayam for life.
Build up your timing gradually.If you feel tired or dizzy, stop and resume after one minute.
Anulom Vilom pranayam –
Close your right nostril with thumb and deep breath-in through left nostril  
then – close left nostril with two fingers and breath-out through right nostril  
then -keeping the left nostril closed  deep breath-in through right nostril
then - close your right nostril with thumb and breath-out through left nostril.
This is one cycle of anulom vilom.
Repeat this cycle for 15 to 30  minutes twice a day.
Children under 15 years – do 5 to 10 minutes twice a day.
You can do this before breakfast/lunch/dinner or before bedtime or in bed.Remember to take deep long breaths into the lungs.You can do this while sitting on floor or chair or lying in bed.
