A heart rate monitoring method is disclosed. The method includes steps of monitoring the heart rate current of the test person within a monitoring period to form a heart rate waveform by a monitoring unit； judging a plurality of waveform turning points of the heart rate waveform within a sampling period by a process unit； accessing points of time corresponding to the plurality of waveform turning points for computing a plurality of time periods between the adjacent waveform turning points by the process unit； and judging the relations between the plurality of time periods to obtain the heart rate of the test person by the process unit.一種心率偵測方法，其包含：藉由檢測單元量測待測者在量測時間內之心率電流，以形成心率波形圖；藉由處理單元判斷取樣時間內之複數個波形轉折點；藉由處理單元讀取複數個波形轉折點當中相鄰的兩個波形轉折點所對應的時間點，計算複數個時間間距；以及藉由處理單元判斷複數個時間間距之間的關係，以獲得待測者之心率。
