What department should I visit for symptoms of palpitations, shortness of breath, and chest tightness?

The symptoms of palpitations, shortness of breath, and chest tightness may involve diseases of multiple systems; therefore, the choice of department for medical consultation should be determined according to the patient's specific condition. Generally, the following departments may be considered: 1. **Department of Cardiovascular Medicine**: If the patient perceives the symptoms as mild and non-continuous—occurring intermittently—such symptoms as palpitations, shortness of breath, and chest tightness may be caused by heart diseases, such as arrhythmia, heart failure, or coronary artery disease. Doctors in the Department of Cardiovascular Medicine will assess cardiac condition through diagnostic tools such as electrocardiogram (ECG) and echocardiography, and formulate corresponding treatment plans. 2. **Department of Respiratory Medicine**: If the patient simultaneously experiences respiratory symptoms such as coughing and sputum production, these symptoms may be caused by respiratory system diseases, such as chronic obstructive pulmonary disease (COPD), bronchial asthma, or pneumonia. Doctors in the Department of Respiratory Medicine will evaluate pulmonary condition through chest CT scans, pulmonary function tests, and other diagnostic methods, and provide appropriate treatment recommendations. 3. **Emergency Department**: If the patient's symptoms are acute and severe—for example, sudden angina or myocardial infarction—the patient should immediately visit the Emergency Department for prompt evaluation and initiation of emergency interventions. Patients experiencing symptoms of palpitations, shortness of breath, and chest tightness should choose an appropriate department based on their own symptoms and preliminary diagnosis by a physician.
