The spatial vectorcardiogram in left ventricular hypertrophy.
A study of 90 patients with left ventricular hypertrophy revealed a typical configuration of the spatial vectorcardiogram in most of the subjects. Typically the QRS stY-loop was smooth, wide and rounded, inscribed in a counterclockwise direction and placed largely to the left and above the iso-electric point in its frontal plane projection. The left sagittal plane projection of the QRS stY-loop...
متن کاملThe Vectorcardiogram of Left Ventricular Hypertrophy
DESPITE several studies, no definitive criteria for the vectorcardiographic diagnosis of left ventricular hypertrophy (LVH) have been proposed. Some reports have been limited to the analysis of cases of the systolic overload type of LVH' while others have failed to define specific criteria for the diagnosis or have emphasized the wide overlap of the findings in LVH with those of the normal popu...
متن کاملElectrocardiogram and Vectorcardiogram in Right 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.
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 ...
