Sudden death is a health problem with a rate of one in every thousand inhabitants per annum. The crisis appears suddenly, although the prompt application within a period of a few minutes of an elecrtical discharge from a defibrillator makes the difference between life and death. Persons with a high risk of suffering sudden death have an internal automatic defibrillator (IAD) implanted.

Between 800 and 1000 people die in Gipuzkoa each year as a result of sudden death. These deaths are thus certified because the fatal outcome is unexpected. It affects apparently healthy persons or ill people but who lead normal lives. In many cases the outcome itself is the first sign of the illness.

Most cases have a cardiovascular origin. The cardiac rhythm undergoes a change known as ventricular fibrillation. This involves a very rapid arrhythmia - more than 400 beats a minute. The heart cannot pump blood and it stops.

Given a case of sudden death, it is vital to administer treatment immediately. If it is not administered within ten minutes, death is certain. On the other hand, if the treatment takes place within two minutes, there is a 100% survival rate. An electrical discharge with a defibrillator makes the difference between life and death. This is why, in order to avoid avoidable deaths, there is an increasing number of public locations where automatic, user-friendly defibrillators are installed.

Although in half of the cases the symptoms manifest themselves unexpectedly, there are persons who have a higher risk of dying suddenly. These are patients with cardiac complaints or who have already had a heart attack. Their risk can be quantified. In some cases, to avoid the crisis and thereby, death, an IAD is implanted. Policlnica Guipzcoa and the Hospital Donostia are two of the centres where implants are carried out.

These devices consist of a number of wires connected to the heart and to a central unit located under the skin; the p
