With the passing of each day, our viscera (internal body organs) get stressed. But especially in the case of key part of the circulatory system, heart, scientists have developed the remarkable devices for the continuous beating of the heart. Among these devices defibrillator is the one, which have saved life of so many people since 1947. But unfortunately defective defibrillator leads to the death as five death cases have already been reported.

Defibrillation is the process used to treat the life-threatening heart arrhythmias and in ventricular tachycardia. In this procedure an electric dose is being given by the defibrillator to the affected heart. This electric pulse depolarizes the mass of the cardiac muscles, cease the arrhythmia and reestablish the normal rhythm of the natural pacemaker of body, in the sinoartrial node of the heart.

Defibrillator works well in the presence of other instruments. However, while working with heavy industrial or electrical machinery, it could be harmful. So there is a restriction that if you are implanted with defibrillator you have to make sure that the equipment which you are going to use is in excellent working condition. This caution is essential while using machinery especially that generate magnetic field.
