How does an automatic defibrillator work with a person who has just had a heart attack?
One of the main and most serious complications of an acute myocardial infarction is the development of ventricular fibrillation. Ventricular fibrillation is an arrhythmia that, except on very exceptional occasions, can only be treated by defibrillation. Failure to defibrillate early usually results in death.
Is it beneficial for the population to have automatic defibrillators in public places?
Of course it is very beneficial. Properly treated ventricular fibrillation is a complication that does not usually leave sequelae. However, untreated, it will most likely lead to the person’s death.
What is the point of this if ordinary people do not know how to use it?
Current defibrillators can be found in subways, means of transport, supermarkets, sports facilities, etc. They are very easy to use: just follow the steps indicated by an automatic voice message.
Is it possible to use an automatic defibrillator without the appropriate knowledge, and can this be harmful to the person suffering a heart attack?
We can say that defibrillators are very safe. They will only defibrillate if the rhythm they detect is appropriate. If it is not, they will not discharge. Therefore, the only thing that a person who is not a healthcare worker should be afraid of is not using it. A person with ventricular fibrillation can be said to have lost everything. Only proper and early defibrillation will be able to bring that person back to life.
Where should these defibrillators be placed?
The answer is easy: the more the better.
