My husband is in heart failure. After a 7 day in hospital he received a defibralator/pacemaker combo. Normally an in and out procedure. We are still here as his phosphorus and potassium levels keep depleting. He is craving the old style brine dill pickles and friends and family have persuaded me to give in and give him a treat. Could these occasional pickles be the cause for depleting both the phosphorus and potassium levels? He cannot be released until his potassium level rises.
