Analisis Sinyal Elektrokardiogram Menggunakan Metode Fast Fourier Transform U…

ABSTRACT This study aims to analyze electrocardiogram (ECG) signals using the Fast Fourier Transform (FFT) method to support heart rate diagnosis. The data used consists of nine recordings of patient ECG signals obtained in graphic form, then converted into numerical data using PlotDigitizer software. Furthermore, the data was analyzed in the frequency domain using the FFT algorithm formulated…
