摘要註
心電圖(Electrocardiogram, ECG)是診斷心律不整的關鍵工具,能夠根據心臟在收縮與舒張過程中產生的電訊號變化,有效偵測異常節律。本研究設計了一種基於深度學習的卷積神經網路(Convolutional Neural Network, CNN)模型,用於分類五種類型的心跳。研究以 MIT- BIH 心律不整資料庫為基礎,專注於 MLII 通道,採用短時傅立葉變換 (Short-Time Fourier Transform, STFT)將一維信號轉換為二維時頻譜圖作為模型輸入。實驗結果顯示,本方法達成了準確率 86.16%、靈敏度 86.16%、特異性 96.54%;相較於傳統心律不整檢測方法,其準確率提升 7%至 38%,靈敏度提高 38%,展現出更優的分類性能與臨床應用價值。. Electrocardiogram (ECG) is a key tool for diagnosing cardiac arrhythmia. It can effectively detect abnormal rhythms based on the changes in electrical signals generated by the heart during contraction and relaxation. In this study, a deep learning-based convolutional neural network (CNN) model was designed to classify five types of heartbeats.The study is based on the MIT-BIH arrhythmia database, focusing on the MLII channel, and using short-time Fourier transform (STFT) to convert one-dimensional signals into two-dimensional spectrograms as model input. Experimental results show that this method achieved an accuracy of 86.16%, a sensitivity of 86.16%, and a specificity of 96.54%; compared with traditional arrhythmia detection methods, its accuracy was increased by 7% to 38%, and its sensitivity was increased by 38%, showing better classification performance and clinical application value..
