Trial of a New Cardiac Mass Screening System in School Children : Use of portable computer system for heart sound and electrocardiogram : A preliminary report : Proceedings of the II. Conference on Prevention for Rheumatic Fever and Rheumatic Heart Disease

We stressed the importance to check consequent voltage change dependent on the etiopathogenetic varieties of the disease. The voltage showed rapidly increasing curves in cases with non-specific pericarditis, which would mean the myocardium showing inflammatory enlargement resulted from supermyocarditis after affection. Contrastly, those of secondary ones were not significantly changed. Those findings on voltage change are very useful guidline to diagnose the disease particularly in cases with vague synptoms and/or cases without obvious finding in the eary stage, besides to lend making differential diagnosis on the varieties of the disease.
