متن کاملMechanisms of Exercise Intolerance
Background—A decreased ratio of early to late diastolic mitral inflow velocities (E/A 1.0) reflects slowing of left ventricular (LV) relaxation. This finding is widely believed to indicate significant diastolic dysfunction. However, E/A 1.0 is common during normal aging and often is not associated with symptoms of heart failure. We asked (1) whether slowed LV relaxation is associated with exerc...

متن کاملExercise intolerance and exercise-induced bronchoconstriction in children.
Respiratory symptoms at rest or during exercise may restrain the physical capabilities required for normal motor and psychosocial development in children. The most frequent cause of exercise intolerance, apart from poor physical fitness, is exercise-induced bronchoconstriction (EIB), which may occur in some healthy children and in children with asthma. It is proposed that hyperventilation durin...
متن کاملExercise Intolerance in Chronic Heart Failure
xercise intolerance is a major clinical manifestation in patients with chronic heart failure (CHF). It was originally considered to be the result of a failure of perfusion to the exercising musculature and consequent early onset of intramuscular acidosis. Under this theory, cardiotonic agents were administered to improve symptoms and exercise tolerance in patients with CHF. However, the therapy...
