Sudden cardiac arrest can happen without warning, but sometimes there are symptoms that shouldn't be ignored.
Potential warning signs include:
• Fainting or unexplained dizziness, especially during exercise
• Chest pain or discomfort
• Shortness of breath
• Racing or irregular heartbeat
• Unexplained seizures
These symptoms don't always mean someone has a heart condition, but you should discuss them with a healthcare professional.
Knowing what to look for and speaking up about concerns can make a difference.
