Have you ever seen boxes hanging up on walls that say ‘EMERGENCY DEFIBRILLATOR’ and wonder what it is? What is it used for? Well they can be used for heart attacks. But what is a heart attack? A heart attack is when a blood clot blocks the blood flow to the heart. Without the blood, the tissue loses oxygen and can simply die. To prevent one from happening look for the symptoms. Symptoms include discomfort in the chest, nausea, indigestion, heartburn, abdominal pain, shortness of breath, lightheadedness, and cold sweating. If you catch these symptoms before the attack occurs you can go to the doctors and get it treated. The longer you wait to get it treated your chance of survival goes down and the damage on your heart goes up and so does your risk of death . Defibrillators can be used to restore a normal heartbeat by sending an electric pulse or shock to the heart. Emergency defibrillators can be found in all sorts of places. After going to the hospital they’ll continue going to checkups to check in on the heart and if the treatments did what they needed them to do. Depending on how much damage the heart attack did the patient can go back to normal activities (unless they include smoking, and eating unhealthy food). To conclude heart attacks are dangerous but they  can be prevented and treated.
