The comedian says in a statement issued Monday that she doesn't know what caused the chest pain "but it's fine."
DeGeneres says she started having chest pains Sunday night and woke up feeling tightness and heaviness in her chest. She compared the feeling to having two cats on her chest.
She said the pains lingered when she came to work, so she called 911 "to be safe." She joked the paramedics may have overreacted, saying multiple trucks and ambulances showed up on the Warner Brothers lot and appeared "like one marching band short of a parade."
She thanked the medical responders "for caring so much."
