What are the symptoms of heart contusion?

Depends on severity. There may be no symptoms while the ekg and blood samples have the appearance of an acute myocardial infarction (heart attack). Some people have chest pain that can mimic a heart attack or pleurisy. Arrhythmias/palpitations may occur. A severe contusion can cause a pericardial effusion with tamponade, leading to death if untreated. The symptoms are shortness of breath and low blood pressure.
