Key result
Teleroentgen measurements evaluate baseline heart size in male soldiers with active combat experience.
Why the study?
Statistics on heart size of soldiers who had active fighting service overseas and were free from cardiac symptoms were lacking.
Cross-Sectional (n=277)
This historical study aimed to establish normative teleroentgen measurements of heart size in asymptomatic soldiers with active combat experience.

Historical soldier heart-size norms offer uncertain modern reference; leaves open validation in contemporary cohorts and imaging.
Teleroentgen measurements were made on 277 men selected from the orthopedic service for the purpose of securing statistics on the heart size of soldiers who had had active fighting service overseas Only those men were selected for this study who had been free from cardiac symptoms during their period of military service and who had had no infectious disease since entering the army. Each man whose measurements are reported had completed his training without difficulty, had taken full part in forced marches overseas and had had at least three months of active fighting. Most of the measurements were taken immediately before the men were discharged from the hospital, and all the patients were well advanced in convalescence. The same technic was followed throughout the series. All plates were from one to four seconds' duration, depending on the thickness from the plate. The upright of the tube stand was ruled in

BERTNARD SMITH (1920) conducted a cross-sectional in Normal soldiers (n=277). Teleroentgen measurements was evaluated on Heart size statistics. Teleroentgen measurements were performed on 277 normal male soldiers with active fighting experience to secure statistics on heart size, though specific quantitative results are not reported.
