Sudden Cardiac Arrest

            
             Before someone even realizes what is happen to them they are unconscious and their heart has ceased beating. This is the nightmare that is sudden cardiac arrest. It kills nearly four-hundred thousand people each year. This is a baffling number considering the fact that there is no way to predict sudden cardiac arrest, except that those with a history of heart disease may be at a slightly higher risk. For these reasons it has become an ever-increasing priority to inform the public on what sudden cardiac arrest is, what to do if someone you know is having a sudden cardiac arrest, what the preventative methods are for sudden cardiac arrest, and what treatments are available to those that have survived a sudden cardiac arrest.
             So, the question is, "What is sudden cardiac arrest?" Well, sudden cardiac arrest is, basically, a rhythmic disorder of the heart in which the heart is no longer beating or it beats too little to keep the person alive. There are different kinds of rhythmic disturbances that the heart can go through during sudden cardiac arrest. .
             The first such disturbance is called a systole, in which there is no longer an electrical impulse reaching the heart, thus there is no heart beat. Two other disturbances in the heart are called ventricular tachycardia and ventricular fibrillation. Ventricular fibrillation is when the electrical activity taking place in the heart is very erratic. This causes the heart to move very erratically, yet it does not pump blood. Ventricular tachycardia is when the heart beats too rapidly. When either of those two said disturbances takes place, it usually results in one of two things, either arrhythmia or bradycardia. Arrhythmia is an irregular heart rhythm in which the heart will suddenly stop. Bradycardia is when the heart rhythm slows down so much that it can no longer sustain life. In either one of these disturbances the onset of symptoms is extremely fast, making it very hard to see coming.
