metadata.value: Ventricular fibrillation is the most common cause of sudden cardiac death and continues to
  be an urgent problem. The aim of the paper was to study the organized activity of canine
  ventricular fibrillation under 1-minute ischemia and 10-minute reperfusion of the heart. A
  ventricular electrogram was recorded and spectral analysis of 10-second segments of the electrogram
  was performed under perfusion, ischemia, and reperfusion of the heart in fibrillation
  using Fast Fourier Transform at 30 frequencies in the range of 0.5–15 Hz. Specific gravity of
  0.5–15-Hz oscillations was determined under perfusion, ischemia, and reperfusion in fibrillation.
  Ventricular fibrillation is characterized by organized activity during perfusion, ischemia,
  and reperfusion as evidenced by dominant frequency structure. Perfusion of the heart during
  ventricular fibrillation increases the stability of the organized structure of fibrillation to
  ischemia: under 1-minute ischemia after 10-minute perfusion, the frequency of dominant
  oscillations decreases by only 0.5 Hz while organized activity does not decrease. Reperfusion
  in fibrillation is characterized by the transient 1.5-Hz increase of frequency of dominant oscillations
  and by a 15 % decrease of organized fibrillation activity at the 1st minute of reperfusion
  after 1 minute of ischemia. The organized structure of fibrillation is more sensitive to reperfusion
  than to ischemia.
