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.
