| 摘 要： | 用乙酰胆硷（Ａｃｈ）复制家兔实验性心房纤颤模型，采用Ｙ导联引导心电信号经快速傅里叶转换对心房电活动进行频谱分析。结果显示：心房纤颤时心房电活动频谱明显异常，表现为低频段能量增加，１－４Ｈｚ和１－２０Ｈｚ频段能量比正常状态明显增大，１－４Ｈ／５－１０Ｈｚ比值和１－２０Ｈｚ／＞２０Ｈｚ的比值都明显变大，而最高频率明显减小。提示心房纤颤发作时心房电频谱中低频成分能量增加。

| Abstract: | Reprodticing the model of experiment atrial fibrillation on rabbitswith acetylcholine(ACH ).The results showed that the atrial activity spectrumgramwere significantly unnormal during the atrial fibrillation. The power in lower frequencyincreased.1 -4Hz and 1-20Hz spectrum power were significantly higher than that innormal and the highst fregtiency were decreased.It suggested that the power in lowerfrequency of atrial activity spectrum increased during atrial fibrillation. |
