Okay, Lovatics. Try... at least please try... not to black out. Because we think you just might be about to have a “heart attack.”

Demi Lovato has released the name of her new single. And its release date. And a new preview video.

My new single #HeartAttack available March 4,” the pop tart tweeted on February 13, along with a link to a preview video, which contains a clip of the new song.

In addition, fans are speculating that Demi’s new album will be titled, “Blackout,” after her Twitter, Facebook, Tumblr and website all went black. Her record label, Hollywood Records, tweeted about “a couple more clues,” and #DemiBlackOut soon started trending on Twitter.

Take a listen to the preview video, then sound off to let us know what you think of the new single so far.

Well, provided you’ve stopped flailing and picked yourself off up the floor. Uh... is there a doctor in the house?
