A cardiac pacing device is disposed between an atrium and an auricle on the same side of a heart, and includes a blocking member and an adjusting member, wherein the blocking member is disposed at a communication opening of the atrium and the auricle so as to block the auricle； and the adjusting member is disposed on the blocking member and is in contact with the heart through the blocking member to pace the cardiac rhythm of the heart, wherein the adjusting member includes a storage module for storing a preset rhythm corresponding to the normal heartbeat of a heart, a sensing module for capturing the heartbeat rate of the heart, an analysis module electrically connected with the storage module and the sensing module for comparing the difference between the heartbeat rate and the preset rhythm, and an actuation module electrically connected with the analysis module for adjusting the cardiac rhythm.一種心律調節裝置，設置於一心臟同一側的心房與心耳之間，並包含一封阻件及一調節件，該封阻件設於該心房與該心耳的一連通開口以封堵該心耳；該調節件設於該封阻件上且透過該封阻件接觸該心臟，以調整該心臟之心律。
