4. Bing Ai: How can I quickly determine whether there is a problem with my heart? Last night I suddenly experienced symptoms of a heart attack, but I am allergic to nitroglycerin and don't know what emergency medication to take, so I can only try to recover on my own.

Answer: The quickest ways to check for heart problems are cardiac auscultation and electrocardiogram. However, some patients with coronary heart disease show no abnormalities in either cardiac auscultation or ECG; this is due to transient coronary artery spasm. Treatment based on symptoms is acceptable, but you should not blindly choose medications yourself—instead, go to a specialized hospital immediately.
