In cardiology a ventricular escape beat is a self-generated electrical discharge initiated by, and causing contraction of, the ventricles of the heart; normally the heart rhythm is begun in the atria of the heart and is subsequently transmitted to the ventricles. The ventricular escape beat follows a long pause in ventricular rhythm and acts to prevent cardiac arrest. It indicates a failure of the electrical conduction system of the heart to stimulate the ventricles (which would lead to the absence of heartbeats, unless ventricular escape beats occur).
Famous quotes containing the words escape and/or beat:
“No evil dooms us hopelessly except the evil we love, and desire to continue in, and make no effort to escape from.”
—George Eliot [Mary Ann (or Marian)
“When I was a kid I used to tell myself the moon was a silver gong and if I could climb high enough to beat on it with both hands all my wishes would come true.”
