I Have A Weak Heart Valve, And For The Last

i have a weak heart valve, and for the last three days i have had hicups. today however they are so bad i am having trouble with the fact that sometimes i hicup so many times in a row i loose my breath and am having to settle myself down to catch my breath. i also suffer from anxiety so this is getting extremely difficult. what should i do? and could this be a sign of serious illness?
