  1. Flatline

    A flatline is an electrical time sequence measurement that shows no activity and therefore when represented, shows a flat line instead of a moving one. It almost always refers to either a flatlined electrocardiogram, where the heart shows no electrical activity, or to a flat electroencephalogram, in which the brain shows no electrical activity. Both of these specific cases are involved in various definitions of death. Some consider one who has flatlined to be clinically dead, regardless of eventual resuscitation or lack thereof, whereas others insist that one is alive until the moment of brain death. This is mostly used in the medical industry when a person's pulse has stopped, indicating a flat line on the heart monitor. When a patient displays a cardiac flatline, the treatment of choice is an injection of vasopressin and chest compressions. Successful resuscitation is generally unlikely and is inversely related to the length of time spent attempting resuscitation. Despite defibrillation commonly appearing on medical dramas as a remedy for asystole, it is usually not done when there is a total absence of electrical activity, as it could actually make it more difficult to restart the heart.

Examples of flatline in a Sentence

  1. Chrissy Teigen:

    It was a sad existence. There were no highs. It was a flatline of life for a few months, you hear these horrific stories of people not seeing their child as theirs, or wanting to hurt them, and I never felt that way. That's why I put off getting it checked as I hated Chrissy Teigen, not my child.

  2. Robert Watts:

    Touring remains the big earner for many of the stadium-filling acts on our musicians' list, but the Covid outbreak has wrecked concert plans and so we expect the wealth of many of these musicians will flatline over the coming year.
