Ellen DeGeneres: Thanks For Caring, TMZ!!

Ellen DeGeneres wants everyone to know ... her heart scare that triggered a 911 call Monday morning has been happily resolved ... and she gave TMZ special mention for spreading the word, Paul Revere-style.

Ellen taped her show hours after paramedics arrived on the Warner Bros. lot to check her out. She says she felt a tightness and heaviness in her chest and felt she needed to have it checked out.
