The difference between cervical heart syndrome and cardiac neurosis mainly lies in the different causes and symptoms. 1. Etiology: cervical cardiac syndrome is mainly due to aseptic inflammation of the cervical vertebrae caused by cervical spondylosis, which stimulates or compresses the nerve roots and blood vessels of the patient, leading to cervical cardiac syndrome. The cause of cardiac neurosis is still unclear, and is considered to be related to a variety of reasons such as neurological type, environmental factors, genetic factors, etc. Therefore, the causes of cervical heart syndrome and cardiac neurosis are different. 2. Symptoms: the main symptoms of patients with cervical heart syndrome are angina pectoris, arrhythmia, hypertension, etc., and patients may also experience numbness of the trunk, weakness, shivering and other symptoms. The main symptoms of cardiac neurosis are palpitations (rapid heartbeat, often accompanied by panic), dyspnea, precordial pain, etc. Patients also suffer from insomnia, dreaminess, anxiety, loss of appetite, dizziness, tinnitus, frequent urination and other symptoms. There are various differences between cervical heart syndrome and cardiac neurosis, and patients should seek medical attention to identify the cause of the disease and follow the doctor’s instructions when they experience uncomfortable symptoms.
