Cardiac arrhythmias do not cause tinnitus. Patients with clinical arrhythmias rarely present with tinnitus as the main complaint, and few patients complain of tinnitus during an arrhythmia attack. Rapid arrhythmias can have a very fast heartbeat. If the heartbeat is fast for a long time and is not corrected in time, cardiac insufficiency and insufficient blood supply to other organs may occur, and individual patients may have ear discomfort or abnormal ear murmur, but this is very rare in clinical practice. In extreme cases, slow arrhythmias may cause inadequate blood supply to vital organs due to a particularly slow heartbeat, starting with inadequate blood supply to the cerebral arteries, or inadequate blood supply to the hearing, causing hearing problems in patients, but very rare.
