Pain in the middle of the chest when lowering the head is not considered to be caused by organic cardiac lesions, and is highly suspected to be caused by cervical-cardiac syndrome, cervical spondylosis, or costochondritis. However, in order to further exclude or clarify whether the pain is caused by organic cardiac lesions, it is recommended that the patient can have an electrocardiogram, cardiac ultrasound, chest X-ray, and cervical spine MRI, which will help to further clarify the diagnosis. During the onset of discomfort, it is recommended that patients take heart pills to see if the pain can be relieved. If the pain can be relieved, it cannot be ruled out that it is caused by insufficient blood supply to the myocardium. If it cannot be relieved, and no abnormality is found in the examination, it is considered that it is most likely to be caused by cervical-cardiac syndrome.
