During aerobic exercise the performance of the heart is based on heart rate, the amount of blood pumped per beat (stroke volume), and heart contractility, or the forcefulness of each heart contraction. Combined, these variables increase blood flow and oxygen supply to meet the demands of the exercising muscles.
Non-epileptic seizures are paroxysmal events that mimic an epileptic seizure but do not involve abnormal, rhythmic discharges of cortical neurons.[1] They are caused by either physiological or psychological conditions. The latter is discussed more fully in psychogenic non-epileptic seizures.
2 1 What Is a seIzure? A seizure is a temporary loss of control often, but not always, accompanied by convulsions, unconsciousness or both. Most common are epileptic seizures, or seizures caused by sudden abnormal electrical discharges in the brain. Non-epileptic seizures, on the other hand, are not accom-panied by abnormal electrical discharges. They have been previously called pseudoseizures, but that term is mislead-ing. These seizures are quite real, and people who have them do not have conscious, voluntary control over them.
