The present invention discloses an arrhythmia detecting device comprising an electrocardiographic measuring unit, an ECG processing unit and a cardiac arrhythm determination unit. The ECG measuring unit is configured to measure a plurality of ECG parameters. The ECG processing unit is coupled to the ECG measurement unit and configured to process the ECG parameters and generate a plurality of ECG features. The arrhythmia determining unit is coupled to the electrocardiographic processing unit and configured to determine at least one cardiac rhythm result based on at least one of the electrocardiographic characteristics. Using this creative heart rate detection device and its related systems, users can observe the ECG of themselves, friends or family members at any time, and monitor whether there are signs of arrhythmia, to achieve early detection of early prevention of heart disease prevention.本創作揭露一種心律不整偵測裝置，包括有一心電訊號量測單元、一心電訊號處理單元和一心律不整判斷單元。該心電訊號量測單元用以量測複數心電參數。該心電訊號處理單元，與該心電訊號量測單元連接，並用以處理該等心電參數，及產生複數心電特徵。該心律不整判斷單元，與該心電訊號處理單元連接，並用以根據該等心電特徵中之至少一心電特徵判斷至少一心律結果。運用本創作之心律不整偵測裝置及其相關系統，使用者可隨時觀察自己、朋友或家人的心電圖，以及監測是否有心律不整的徵兆，達到早期偵測早期治療心臟病的預防功效。
