If the patient has rheumatic heart disease, the main symptoms include palpitations, chest tightness, and shortness of breath after activity, as well as swelling in both lower extremities. If wheezing symptoms occur, some cardiotonic drugs can be used in treatment to improve the patient's symptoms.

Currently, treatment primarily focuses on symptomatic relief and improving the patient's cardiac and pulmonary functions. During this period, it is important to actively prevent complications. If the patient's symptoms occur abruptly, it is crucial to seek immediate medical attention at a hospital. Sometimes, infusion therapy and low-flow oxygen inhalation are required to effectively alleviate the patient's current symptoms of palpitations, chest tightness, and breathing difficulties.
