Cardiac arrest can occur suddenly, but there are often warning signs, especially in young adults. These signs may include chest pain, dizziness, palpitations, or fainting. Shortness of breath, unexplained fatigue, and racing heartbeats can also be indicators. It’s crucial not to ignore these symptoms, as they could signal underlying heart issues. Seeking prompt medical attention and maintaining a heart-healthy lifestyle are vital for preventing cardiac arrest, even in young adults.
