The rate of regression of ventricular hypertrophy in vectorcardiogram and electrocardiogram after surgery on congenital heart disease

摘要: Summary Scalar electrocardiograms and vectorcardiograms were performed on children with isolated congenital heart defects just before corrective surgery, 7 to 10 days after 6 18 months later. The early late changes statistically analyzed. In 36 cases of pulmonary stenosis there was a reduction right ventricular hypertrophy in cardiograms. 42 secundum atrial defect no significant shown the cardiograms, although cardiograms did show this effect; voltages from left ventricle significantly increased both 49 patent ductus arterious reduced 39 valvular aortic S V 1 seen ECG very rapid surprising may be explained by electrical phenomena or atrophy
