Cerebral infarction can cause cardiac discomfort, which is clinically seen in large cerebral infarction or infarction of hypothalamus or brainstem, resulting in the central autonomic nerve being affected, and the patient can develop cerebrocardiac syndrome.1. Cerebrocardiac syndrome is mainly due to brain lesions that cause the patient to develop cardiac symptoms, which can be symptoms of myocardial ischemia, arrhythmia or heart rate failure. When the patient’s brain symptoms are relieved, the patient’s heart symptoms can also be relieved. 2. Patients with cerebrocardiac syndrome can develop central arrhythmias, mainly due to cerebral infarction lesions affecting the hypothalamus, which in turn leads to central autonomic dysfunction. For the types of arrhythmias, supraventricular arrhythmias are the main clinical cause, and some patients may develop ventricular fibrillation, which may lead to death. Patients with cerebral infarction must be given active treatment, and if heart discomfort occurs, patients should be given relevant examinations and given active treatment.
