Answer:
Onset of STEMI
Step-by-step explanation:
The onset of STEMI involves abrupt and significant chest pain. The pain typically is severe, often described as being constricting, suffocating, and crushing. Substernal pain that radiates to the left arm, neck, or jaw is common, although it may be experienced in other areas of the chest and back. Unlike that of angina, the pain associated with MI is more prolonged and not relieved by rest or nitroglycerin.
