It is estimated that in these patients, if not adequately followed up, syncopal episodes increase the incidence of sudden death by up to 24% within a year of syncope. Syncopes in people with heart disease, such as hypertrophic or dilated heart disease, are more serious. In these cases, the main risk is the consequences of the fall, sometimes serious. Triggers may be strong emotions, anxiety, hot environments, severe pain or simple circumstances such as drawing blood or visiting a sick relative in hospital. Neuromediated syncopes usually occur in young women who are hypotensive, in elderly people with very low blood pressure, partly because they drink little, or in growing adolescents. With the fall, in fact, the subject rebalances the pressure and brings cerebral perfusion to optimal levels. When the brain does not receive enough blood, it ‘flips the switch’ to protect itself. Paradoxically, syncope is a protective factor for the brain. caused by a sudden change in the autonomic or vegetative nervous system. Low-risk syncope is syncope caused by a sudden drop in blood pressure, accompanied, or not, by a slowing of the heart rate. This is the classic fainting spell, or, in medical terms, syncope.Įspecially in summer – due to high temperatures and dehydration – there are frequent visits to the emergency room of patients affected by this event, which is not serious in itself, but which should not be trivialised because it could be an alarm bell of serious diseases, primarily cardiac. You wake up a few seconds later on the floor, most often with someone slapping you back to the real world with a ‘benevolent’ slap. Why does one faint? And what tests determine the causes? Your head is spinning, your vision is blurred and your legs can’t cope. The Head up Tilt Test investigates vagal syncope: what is this alarm bell of the body? loss of consciousness due to a temporary drop in the flow of blood to the brainĭuring the test, the conditions of a syncopal episode are reproduced in a protected environment and under continuous monitoring of blood pressure and heart rate, thus making it possible to assess its origin. The Head Up Tilt Test is an examination that completes the diagnostic process to identify the causes of an episode of syncope, i.e.
