Understanding AED’S. Chemical impulses are what power the human heart beats. Heart beats are made possible by specially structured cells that are known as the pacemakers. Medication, external stimuli, stress, and physical activity are some of the factors that influence the performance of the cells. Chemical impulses in the pacemaker cells can be altered by the factors listed above. One of the most well know heart stimuli but often misunderstood is defibrillation. Defibrillation involves administering jolt electricity to the muscles of the heart. Heart muscles are depolarized when defibrillation is carried out and serves to allow heart beat return to normalcy after the pacemaker is reset. The devices that perform the function of defibrillation are known as defibrillators. There are varying designs and capacities of the defibrillation gadgets. Most of the defibrillators being displayed in the TV’s today are outdated. Defibrillation more commonly occurs through the prophylactic nodes. The nodes are typically attached to a patient’s chest, and this helps to monitor the heart rate. The function of the nodes is to stimulate a shock heart rhythm through an electric shock. Unlike what is shown in movies and TV shows, patients of electric shocks do not convulse. What happens is that the patients experience a small amount of rhythmic contraction of the body muscles. Rather then working in a pattern, ventricular cardiac fibrillation occurs when the ventricle quivers. AED gadget can be found today in the market although the various companies manufacturing them.
