Ventricular fibrillation (VF) in dogs is characterized by a rapid increase in its dominant frequency during the 1st minute of reperfusion followed by its decrease during the 2nd minute of reperfusion. The longer is ischemia in VF, the greater is the increase in dominant VF frequency during reperfusion. The 1st minute of reperfusion is characterized by a 1.2-fold increase in dominant VF frequency after 1-min ischemia in VF, by 1.4-fold increase after 2-min ischemia, by 2-fold increase after 3 min, and by 2.6-fold increase after 4-min ischemia. During the 2nd minute of reperfusion, the dominant VF frequency decreased by 1.1-1.3 times, and during 3rd-10th minutes of reperfusion, the dominant VF frequency is stabilized.
犬心室颤动（VF）的特征是在再灌注的第 1 分钟内其主导频率迅速增加，随后在再灌注的第 2 分钟内降低。VF 缺血时间越长，再灌注期间主导 VF 频率的增加越大。在再灌注的第 1 分钟内，在 VF 缺血 1 分钟后，主导 VF 频率增加 1.2 倍，缺血 2 分钟后增加 1.4 倍，缺血 3 分钟后增加 2 倍，缺血 4 分钟后增加 2.6 倍。在再灌注的第 2 分钟内，主导 VF 频率降低 1.1-1.3 倍，在再灌注的第 3-10 分钟内，主导 VF 频率稳定。
