Influence of respiratory variations on right ventricular function.
Respiratory effort during inspiration, expiration, and the Valsalva manoeuvre changes right ventricular preload and afterload. On inspiration these changes should improve systolic emptying of a larger end diastolic volume and so increase the ejection fraction, whereas on expiration the reverse should be true. The resting right ventricular ejection fraction was measured by first pass radionuclid...
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 کاملDetermination of the Effects of Digoxin on the Right Ventricular Function in Patients Undergoing Pneumonectomy
Introduction: Pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. We have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. Materials a...
متن کاملInfluence of right ventricular stimulation site on left ventricular function in atrial synchronous ventricular pacing.
OBJECTIVES The study investigates the correlation between left ventricular function and QRS duration obtained by alternate right ventricular pacing sites. BACKGROUND 1. Right ventricular apical pacing is associated with alterations of left ventricular contraction sequence. 2. A stimulation producing narrow QRS complexes is supposed to provide for better left ventricular contraction patterns. ...
متن کامل[Acute respiratory distress syndrome, mechanical ventilation and right ventricular function].
Mechanical ventilation in acute respiratory distress syndrome (ARDS) implies an increase in alveolar and transpulmonary pressure, giving rise to major alterations in pulmonary circulation and causing right ventricular functional overload that can lead to ventricular failure and thus to acute cor pulmonale. The condition is echocardiographically characterized by dilatation of the right ventricle...
