Right 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 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...
متن کاملRight ventricular hypertrophy and right bundle branch block.
Wit/i the collaboration of Charles A. Bertrand, M.D., and Frederick R. Mugler, M.D. Electrocardiographic and vectorcardiographic studies on normal subjects and patients with heart disease suggest that criteria for the diagnosis of right ventricular hypertrophy can be improved and simplified. This report proposes new criteria for the electrocardiographic diagnosis of right ventricular hypertroph...
متن کاملRight ventricular hypertrophy: a new "risk factor" for right ventricular infarction?
The right ventricle is a somewhat strange organ; it seems to function as a pump quite well even when its wall is deliberatelydestroyed by a cautery or when its blood supply is severely compromised. Infarction of the right ventricle was long considered rare. on the assumption that the low pressure system had a low oxygen requirement. In recent years. following the report of Cohn et al. (I), it h...
