This means:
“The post claims that if someone has a heart attack at home, performing a particular action within 10 seconds could save their life.”
Breakdown
“If you have a heart attack at home” = describes a potentially life-threatening medical emergency.
“Do this in 10 seconds” = creates urgency and suggests there is a very quick action to take.
“You can save your life” = makes a strong promise about the outcome.
“(1 / 2)” = likely means this is part 1 of a two-part post, with the supposed action revealed later.
Important point
This is potentially dangerous medical clickbait if it suggests there is a secret maneuver that can treat a heart attack in seconds.
If you suspect a heart attack, call your local emergency medical service immediately and follow the dispatcher’s instructions. Don’t rely on a social-media trick or wait to see whether symptoms disappear.
Typical warning symptoms can include pressure or pain in the chest, pain spreading to the arm, back, neck, jaw or stomach, shortness of breath, cold sweating, nausea, or unusual weakness. Symptoms can vary, especially in women and older adults.
A more responsible version:
“Suspect a heart attack? Here’s what to do immediately while waiting for emergency medical help.”
