In brief: Low K SOB
YES. It can impair heart pumping.
Also so can cause generalized tiredness. Need lots more details. So contact your team or consult with me.

In brief: No
Electrolyte abnormalities do not typically cause shortness of breath; sometimes very low calcium levels and low magnesium levels and low phosphate levels can be associated with muscle weakness which could affect the diaphragm causing shortness of breath.
This is uncommon.
