What are common indicators of cardiac emergency?

Common indicators of a cardiac emergency include chest pain or discomfort, which may feel like pressure, squeezing, or fullness, often accompanied by pain radiating to the arms, back, neck, jaw, or stomach. Other symptoms can include shortness of breath, nausea, lightheadedness, or sweating. It's crucial to seek immediate medical attention if these symptoms occur, as they may indicate a heart attack or other serious cardiac conditions.
