An algorithm for detection of ECG changes based on the Fourier transform is presented. The realisation of the algorithm was programmed on a minicomputer and could detect both large and subtle changes in an ECG waveform. The cardiac arrhythmias used in the study included normal sinus rhythm; premature atrial contraction; premature ventricular contraction; first, second, and third degree blocks; atrial and ventricular fibrillation and ventricular tachycardia. The algorithm was used to detect rhythm changes, but it is possible that, using it, a unique specification for a waveform at any frequency could be obtained.
提出了一种基于傅里叶变换的心电图变化检测算法。该算法在小型计算机上编程实现，能够检测心电图波形中的大变化和细微变化。研究中使用的心律失常包括正常窦性心律、房性早搏、室性早搏、一度、二度和三度房室传导阻滞、心房颤动、心室颤动和室性心动过速。该算法用于检测心律变化，但使用它有可能获得任何频率下波形的唯一特征。
