QRS-Voltage Criteria for Left Ventricular Hypertrophy in a Normal Male Population
In this study the range and upper limits of seven QRS-voltage criteria for left ventricular hypertrophy have been established in healthy, fit male young and middle-aged populations. The upper limits of normal for younger and older populations differ considerably. Agreement with the published literature occurred with some of the criteria in the older age group.
