CARDIOGRAPHIC PATTERNS IN SYSTOLIC AND DIASTOLIC OVERLOAD OF THE LEFT VENTRICLE

Abstract
The vcg and ecg of patients with left ventricular hypertrophy have been studied. These have been divided into two groups; the first includes those with an increased left ventricular stroke output without a raised pressure (diastolic overload), and the second includes those with increased left ventricular pressure with a normal stroke output (systolic overload). There appears to be considerable overlap in the cardiographic patterns in the two groups, and it has not been possible to separate them clearly in clinical practice.
