If a patient has an excessive amount of pericardial effusion, symptoms such as palpitations, chest tightness, and difficulty breathing can occur. Currently, the treatment primarily focuses on symptomatic relief. If there is excessive pericardial effusion, symptoms such as chest tightness, palpitations, and difficulty breathing may occur. I personally suggest going to the hospital for a cardiac echocardiogram to further confirm the diagnosis and determine the treatment plan. For simple pericardial effusion, if the amount is relatively small, it can be temporarily observed without treatment. However, for cases with excessive pericardial effusion, it is necessary to perform a pericardiocentesis to remove the fluid and improve cardiac function. During this period, it is still necessary to actively monitor the patient's blood pressure, heart rate, and pulse changes, and address any rapid heart rate.
