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.
Intractable epilepsy is a seizure disorder in which a patientâs seizures fail to come under control with treatment. These seizures are sometimes also called âuncontrolledâ or ârefractory.â. Frequently intractable epilepsy interferes with a patientâs quality of life. People who are not seizure-free need to be careful about possible accidents during a seizure. Patients with intractable epilepsy need to take caution while in water, near busy streets or railway platforms, and often are unable to drive.
