Hemodynamic versus adrenergic control of cat right ventricular hypertrophy.
The purpose of this study was to determine whether cardiac hypertrophy in response to hemodynamic overloading is a primary result of the increased load or is instead a secondary result of such other factors as concurrent sympathetic activation. To make this distinction, four experiments were done; the major experimental result, cardiac hypertrophy, was assessed in terms of ventricular mass and ...
متن کاملRight ventricular hypertrophy.
The electrocardiograms of 22 cases showing isolated right ventricular hypertrophy at autopsy were examined for changes suggestive of right ventricular hypertrophy. Only 5 of 22 cases fulfilled at least one of the criteria of Sokolow and Lyon and only three could be diagnosed as having right ventricular hypertrophy by the criteria of Myers, Klein and Stofer. Factors contributing to the developme...
متن کاملPolycythemia and Right Ventricular Hypertrophy.
• The chronic hypoxia of high altitude produces an elevated pulmonary arterial pressure" resulting in right ventricular hypertrophy.' Cournand has proposed that the pulmonary hypertension and subsequent right ventricular hypertrophy found in patients with chronic pulmonary disease are associated with polycythemia, hypervolemia, and increased cardiac output secondary to the hypoxemia present in ...
متن کاملRight ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...
متن کاملEditorial note on right ventricular hypertrophy.
It has long been clear to me, and no doubt to many others, that extreme right axis deviation (large SI and RIII with insignificant RI and SIII) is common in many forms of pulmonary stenosis and other congenital heart diseases, much rarer in mitral stenosis (where a common finding is a small R in lead I and a larger R in leads II and III, the rRR type), and quite unusual in chronic pulmonary dis...
