If you have respiratory tract infection before 1 week, and you have chest tightness, palpitation and shortness of breath after acute pharyngitis and acute tonsillitis, you can go to the hospital for ECG examination. Sinus tachycardia, I degree atrioventricular block, elevated myocardial enzymes, etc. In severe cases, there may be enlargement of the heart, which can be diagnosed by ECG examination, clinical symptoms and medical history.
