An arrhythmia relief device for automatically detecting pulse rate and massaging arm is disclosed. The arrhythmia relief device comprises: a belt body, a detecting unit, a processing unit and a massaging unit. The processing unit receives detecting signal and determines whether the pulse rate of user in a preset time interval comply with a preset value according to the detecting signal. If the pulse rate of user in a preset time interval does not comply with the preset value, the processing unit sends a driving signal to the inflatable component to repeatedly inflate and deflate the airbag such that the force value of the belt body can be changed with a preset massaging mode by the massaging unit.本發明揭示一種自動偵測脈搏頻率及按摩手臂之心律不整緩和器,包含:帶體、偵測單元、處理單元及按摩單元。處理單元接收偵測單元的偵測訊號並依據偵測訊號判斷使用者於預設時間區間內的脈博頻率是否落於一預定值範圍內,若使用者於預設時間區間內的脈博頻率並未落於預定值範圍內,則處理單元發出一驅動訊號至按摩單元之充氣件,以令充氣件經由通道對氣囊反覆充氣及洩氣,使得按摩單元以一預設按摩模式改變帶體的施壓力之數值。10‧‧‧帶體12‧‧‧內側14‧‧‧外側20‧‧‧偵測單元30‧‧‧處理單元40‧‧‧按摩單元42‧‧‧充氣件44‧‧‧通道46‧‧‧氣囊50‧‧‧設定單元60‧‧‧定時單元
