The cardiac defibrillator

The external automatic cardiac defibrillator should be used in the event of cardiac arrest . Since May 2007, a decree authorizes anyone to use a cardiac defibrillator fully automatic external, in case of emergency .

Many cities including Paris are equipped with these devices to help save a maximum of people victims of a heart attack.

Devices in the streets, sports clubs ...

Every year, around 50, 000 people in France are victims of sudden death. In the vast majority of cases, this is the result of an abnormal heartbeat: the contractions become ineffective (the heart starts ventricular fibrillation).

The defibrillator is this device which allows - thanks to an electric shock - to resynchronize the beats of the heart to make it start again normally.

During a cardiac arrest, the chance of survival decreases by 10% every minute. For this reason, it is essential that a defibrillator be used as quickly as possible. The installation of devices in municipal services, sports clubs, city streets, can save a greater number of people victims of a heart attack.

A progressive installation in cities

Towns like Montbard, Hyères, or Issy-les-Moulineaux have pioneered the installation of defibrillators in municipal services and public spaces. In Paris, these devices have been gradually put in place in libraries, museums, sports stadiums, major arteries of the city, and in tourist places.

Correct an abnormality of the heartbeat

Sudden death often strikes without warning. In the vast majority of cases, it has a cardiac origin (abnormal heart rhythm), and can be caused by a myocardial infarction that occurs more often in people:

  • high blood pressure,
  • an excess of cholesterol,
  • diabetes,
  • in smokers (or former smokers).

But this anomaly of the cardiac rhythm (ventricular fibrillation), can have other origins:

  • cardiomyopathy,
  • heart failure,
  • long QT syndrome ...

Thus, it happens that an athlete "collapses" brutally on the field during a competition or training, victim of a cardiac arrest.

A loss of consciousness

The heart no longer beating normally, blood circulation becomes impossible. The victim loses consciousness. At the same time there is a stop of breathing. Dealing with early cardiac arrest (before 5 minutes) increases the victim's chances of survival.
