A Fortified Method to Screen and Detect Left Ventricular Hypertrophy in Asymptomatic Hypertensive Adults: A Korean Retrospective, Cross-Sectional Study

Figure 1

Measurement of cardiac diameter (CD) and thoracic diameter (TD). On chest PA, a vertical line (dotted line) was traced parallel to the vertebral column. The greatest distances from this line to each cardiac border (CD 1 and CD 2) were summed up to get CD. TD was defined as the greatest width (TD) between the inner surfaces of ribs. CD, cardiac diameter; TD, thoracic diameter; chest PA, posteroanterior chest X-ray.
