摘要
用健康犬以分级递增刺激方式建立不同频率的室性心动过速模型,通过同步记录左室和主动脉压力曲线以及主动脉血流频谱的方法,对室速发作时心室收缩是否有效进行研究。结果证明,记录主动脉血流频谱是判断室速发作时心室收缩效果的快速、无创、简便、可靠的手段。
A mode of ventrieular tachycardia was made in 15 mongrel dogs with incremental pacing, and the ventricular contractive effect was investigated through recording simultaneously the Doppler echocardiography and cardiac catheterization. The results showed that this method of recording the aortic blood flow spectra was accurate in identification of the left ventricular contractive effect.
