While in ventricular fibrillation, the heart is unable to pump life sustaining oxygenated blood to vital parts of the body, particularly the brain. While there are many contributing factors, sudden cardiac arrest can strike people at any time, whether or not they have a diagnosed heart condition. Death from sudden cardiac arrest is unexpected, occurring instantly or shortly after the onset of symptoms. Symptoms of a heart attack include uncomfortable pressure, fullness, or squeezing pain in the center of your chest lasting more than a few minutes. The pain may radiate to your arms, shoulders, or neck.
Some patients report a sudden shortness of breath, fainting, nausea, and profuse sweating.
In a heart attack emergency, you have to make crucial decisions under stress. Calling your doctor may add unnecessary time. When you call 911, describe your symptoms such as severe shortness of breath or chest pain. This ensures a priority dispatch of the Fire Department and Johnson County Ambulance. AED s are easy to operate.
