Near-death symptoms can be seen at the onset of sudden death, but can also be seen in other disease states, so sudden death does not necessarily occur when this symptom occurs.
Near-death sensations are most often seen in acute myocardial infarction, aortic coarctation, pulmonary embolism, and other serious life-threatening illnesses, all of which can lead to sudden death. However, it should be noted that near-death sensation can also be seen in panic attacks (also known as acute anxiety) and other situations, the symptoms last for a period of time can be returned to normal, and generally will not be life-threatening, causing sudden death.
In summary, sudden death does not necessarily occur when a near-death experience occurs. However, because the near-death sensation has the function of suggesting the existence of acute and serious dysfunction of the body, it is necessary to consult a doctor immediately to find out the cause of this symptom, so as to avoid delaying the treatment of certain serious diseases and causing adverse consequences. Do not make blind judgment and dispose of it on your own.
