question: My husband is confused, is tired, normal BP, elevated pulse rate (112) and pulse is erratic.  Has been diagnosed in the past with COPD - does not have difficulty breathing.  Over the past several months , he has experienced several of these episodes where his speech is slurred and has difficulty walking.  He is 64 years old today.  We got ready to go for a bicycle ride and he is apparently having another episode.  I can always anticipate that he will be okay the next morning after 10-12 hours of sleeping.
