What causes palpitations, shortness of breath, and chest tightness in high school students?

In general, palpitations, shortness of breath, and chest tightness in high school students may be caused by anxiety and stress, lack of physical exercise, anemia, asthma, or coronary atherosclerotic heart disease. Different causes require different targeted interventions. It is recommended to seek medical attention promptly when discomfort occurs for early diagnosis and treatment. Specific analyses are as follows:

1. Anxiety and stress: Academic pressure, social stress, and similar factors may lead to emotional tension, causing autonomic nervous system dysfunction and triggering the body's stress response, accompanied by symptoms such as palpitations, rapid breathing, chest tightness, and nausea. These can be improved through psychological support, relaxation techniques, and professional counseling.

2. Lack of exercise: Insufficient physical activity may lead to reduced physical fitness and cardiopulmonary function, resulting in low lung capacity, which can cause shortness of breath and palpitations, along with poor exercise tolerance. Engaging in moderate physical activities such as jogging, swimming, or rope skipping can help improve cardiovascular and respiratory health.

3. Anemia: Anemia reduces blood volume and impairs blood system function, leading to inadequate coronary blood supply and decreased oxygen-carrying capacity of the blood, causing shortness of breath and palpitations. Symptoms may also include fatigue, pallor, and dizziness. Treatment should target the underlying cause of anemia, and medications such as ferrous gluconate syrup, iron dextran granules, or vitamin B12 tablets may be used under medical guidance.

4. Asthma: In asthma, bronchi remain in a state of persistent spasm, and bronchoconstriction restricts airflow, causing rapid breathing and chest tightness, often accompanied by wheezing and coughing. Medications such as compound aminophylline tablets, dihydroxypropyltheophylline tablets, or doxofylline tablets may be used under medical supervision to relieve symptoms, and exposure to asthma triggers should be avoided.

5. Coronary atherosclerotic heart disease: Atherosclerosis of the coronary arteries leads to narrowing of the vessel lumen, resulting in insufficient myocardial blood supply and ischemia-hypoxia, causing palpitations and chest tightness, often accompanied by angina symptoms. Medications such as simvastatin dispersible tablets, atorvastatin calcium tablets, or bisoprolol fumarate tablets may be prescribed to alleviate symptoms.

For high school students experiencing these symptoms, early medical evaluation is recommended. A healthcare professional should conduct a comprehensive physical examination and necessary laboratory tests to determine the underlying cause. Treatment will vary depending on the specific diagnosis. Timely and appropriate interventions, along with maintaining a healthy lifestyle, are crucial for symptom relief and improving quality of life.
