They postulated that a certain range of cardiac contractility and intracardiac circulation is necessary for continued growth and proliferation of the myofibrils. The heart also improves in contractility, resulting in a larger ejection fraction, a larger stroke volume and increased maximal cardiac output. Their aim is to reduce detrusor contractility by their effects on the muscarinic cholinergic receptors of the detrusor muscle fibres. This also disclosed poor cardiac contractility and severe biventricular dilation with tricuspid regurgitation. The data points for each patient were within the 95% confidence limits of normal, suggesting normal left ventricular contractility. The right ventricle showed no evidence of volume overload and had normal contractility. The prognosis depends on right ventricular contractility, which should be evaluated carefully before and after the operative procedure. Defined most simply, contractility is the ability of the cardiac muscle to develop tension. The stress-shortening relation has been used as an index of contractility by a number of authors66"68 without adjustment for preload effects. The approach which we have adopted is based on the assumption that percent fiber shortening is determined by afterload, preload, and contractility. The early results, however, have been encouraging in terms of improvement in left ventricular contractility. Limitations of such testing are the absence of contractility of the heart and the inability to control the filling pressure. Uterine contractility as assessed by abdominal surface recording of electromyographic activity in rats during pregnancy. Thus, an endothelial product is responsible for the decrease in contractility. However, progesterone may also act through a non-genomic mechanism to inhibit contractility. It is easier conceptually to accept an altered contractility of the infundibulum which may be influenced by alterations in vascular resistances. The echocardiogram demonstrated an atrial septal defect within the oval fossa and normal contractility. |
