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.
Organic non-epileptic seizures include seizures due to low blood sugar and can also occur with high blood sugars. They closely resemble epileptic seizures but this is not epilepsy. Epileptic seizures occur due to abnormal electrical activity within the brain.
