Defibrillator is used to monitor the patients suffering from heart conditions. Whenever the defibrillator and automated external defibrillator observes that the patient heart rate is decreasing or it is achieving some cardia arrest condition then it might deliver some electric shocks to the heart so that it could regain its normal pulse rate but sometimes this mechanism could go wrong. Although these machines could produce the electric shocks for saving life but this could go wrong a lot and a research tells that the defibrillators are able to produce the shock accurately 59 percent.
There are cases in which patient tells that the defibrillator delivered an electric shock that was like bomb through their chest. At first the defibrillator must be manufactured in such a way that they are very much less likely to produce any error and their accuracy must be increased. A little misconception about the defibrillation is that it is used to start the heartbeat but actually it stops the quivering of heartbeat and assumes that whenever this dysfunctional heartbeat is stopped then the heart actually restarts or regains its original rhythm.
A defibrillator that is implanted in the patient body for monitoring the heart rate gives patient an electric shock whenever it observes any abnormality in the functioning of the heart. The electric shock caused by this defibrillator is not very minor and it is in real case is very much painful. However, this implanted defibrillation is for the patients having severe heart problems and are almost near on deathbed. People describe the pain of these shocks as being hit by some baseball but this pain actually saves the patient from dying therefore it is preferable technique. The time period for this pain is very short and it usually lasts for couple of seconds.
The intensity and amount of energy that is produced and passed through the heart is different for every patient. The average amount of energy that is transferred to the heart is around 300 joules which is equal to 100 watt power. However, all of this energy is not able to reach the heart but most of the energy is utilized by the resistance of other parts of the body just as skin. The major side effect for the patients going through the defibrillator procedures is the contractions of the muscles especially the muscles of chest and the bones of the ribs. It is recommended for the patient to have a regular check on the ribs and the muscles and bones contractions otherwise there is a high chance that the patient could suffer from fractures.
