Prolonged mean VO2 response time in systolic heart failure: an indicator of impaired right ventricular-pulmonary vascular function.
BACKGROUND In patients with left ventricular systolic dysfunction (LVSD), the rate at which oxygen uptake (VO2) increases on initiation of exercise is inadequate to match metabolic demands. To gain mechanistic insights into delayed VO2 kinetics in LVSD, we simultaneously assessed hemodynamic measurements, ventilatory parameters, and peripheral oxygen usage during exercise. METHODS AND RESULTS...
متن کاملLeft ventricular systolic performance during prolonged strenuous exercise in female triathletes
BACKGROUND: The effect of prolonged strenuous exercise (PSE) on left ventricular (LV) systolic function has not been well studied in younger female triathletes. This study examined LV systolic function prior to, during and immediately following PSE (i.e., 40 km bicycle time trial followed by a 10 km run) in 13 younger (29 PlusMinus; 6 years) female triathletes. METHODS: Two-dimensional echocard...
متن کاملThe influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography
Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...
متن کاملImpaired right ventricular systolic function demonstrated by reduced atrioventricular plane displacement in adults with Marfan syndrome.
AIMS The right ventricle (RV) ejects the same volume of blood at the same rate as the left ventricle (LV). Mild LV dysfunction has been demonstrated in Marfan syndrome (MFS). However, little attention has been paid to the functioning of the RV. The aim of this study was to assess RV function in unoperated adult MFS patients. METHODS AND RESULTS In 66 unoperated (15-58 years) MFS patients and ...
متن کاملProlonged Atrio-Ventricular Block Following Scorpion Bite: A Case Report
This report describes a 55-year-old woman in whom yellow scorpion sting resulted in the development of Mobitz type 1 and transient complete heart blocks unresponsive to atropine administration. It might be concluded that although autonomic involvement including parasympathetic overactivity is present in such cases, other factors such as toxic damage to the cardiac conduction system may play a ...
