We studied the use of first-harmonic Fourier analysis of gated blood-pool images to assess the site of ventricular activation in a group of 12 patients undergoing electrophysiologic pacing studies. We acquired gated blood-pool studies during pacing at up to four sites at each of two different rates. A total of 50 studies were made. At a pacing rate of 100 beats/min, when the pacing electrode was at the right-ventricular apex, 9/13 times the Fourier activation site agreed; at the right-ventricular outflow tract, 7/8; at the anterolateral left-ventricular wall, 4/4. When the Fourier activation site was at the right-ventricular apex, 9/9 times the pacing electrode was there; at the right-ventricular outflow tract, 7/10; in the left ventricle, 4/4. Fourier analysis of gated blood-pool studies can help identify the site of ventricular activation but is not sufficiently accurate to fully replace endocardial mapping.
我们研究了利用门控心血池图像的一次谐波傅里叶分析，来评估一组12例接受电生理起搏研究患者的心室激动部位。我们在以两种不同心率在多达四个部位起搏期间获取了门控心血池研究数据。共进行了50项研究。在起搏心率为100次/分钟时，当起搏电极位于右心室心尖时，傅里叶激动部位在9/13次时与之相符；位于右心室流出道时，7/8相符；位于左心室前外侧壁时，4/4相符。当傅里叶激动部位在右心室心尖时，起搏电极在9/9次时位于该部位；在右心室流出道时，7/10相符；在左心室内时，4/4相符。门控心血池研究的傅里叶分析有助于识别心室激动部位，但准确性不足以完全取代心内膜标测。
