Chocolates and roses may set the heart a-flutter on Valentine's Day, but what if someone's heart truly quit beating — right in front of you? You may never need to jumpstart a heart, but learning how is one of the best steps you can take to save a life — and bring peace to your own heart as well.

All it Takes are a Cool Head and Calm Hands

By now, you surely know who Denny Kellington is. He's the hero who jumped into action and performed cardiovascular pulmonary resuscitation, or CPR, on Buffalo Bills player Damar Hamlin when Hamlin's heart stopped during a game on January 2.

Hamlin had experienced a cardiac arrest, which is the sudden loss of heart function, and is often fatal if a cool head and calm hands don't prevail in the moment. According to the American Heart Association (AHA), a stoppage like this happens more than 350,000 times a year in the US. But as millions witnessed, Kellington performed CPR in the critical first seconds, helping to restore Hamlin's heartbeat until medical workers arrived.

This February, which happens to be Heart Health Awareness Month...Be like Denny! With just one click and a minute-and-a-half of time, you can learn the remarkably simple skill of Hands-Only CPRfrom the American Heart Association (AHA). Should a teen or adult suddenly collapse in front of you, you'll be ready to take matters into your hands.

Call 9-1-1 and put the phone on speaker mode — and ask someone to grab an automated external defibrillator (AED), if one is nearby.

Start CPR, pushing hard and fast.

Cardiac Arrest vs. Heart Attack: They're Not the Same!

While these terms might seem interchangeable, and the conditions are often linked, they're really not the same. According to the AHA, a heart attack happens when blood flow to the heart is blocked. Cardiac arrest happens when an electrical malfunction causes the heart to suddenly stop beating.
