title: An algorithm for on-line, real-time computer detection of ECG changes.
abstract: 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.
