I Am A 64 Yr Old Female. 5'5" 150lb. When

I am a 64 yr old female. 5'5" 150lb. When I get out of bed in the morning and walk to the bathroom sink I feel like I can't catch my breath and my heart is pounding. It takes at least 5 minutes leaning on the counter to get my breath. This is happening every morning and sometimes later in the day. I was having short bouts of irregular heartbeats which my docot attributed to dehydration. Drinking more water seems to have helped. EKG doesn't show any problems.
