  • If you are experiencing symptoms of heart failure that range from mild to severe.
  • When the lower chambers of your heart do not synchronize to work together.
  • If your heart is weak and enlarged as detected during the testing.
  • When your heart failure is not well controlled by medicines and lifestyle changes.
