Abstract
A mini-computer system for PCG [phonocardiographic] interpretation was functioning since 1971. The system can analyze as many as 100 PCG in 3 h. Based on 5 yr experience, computer interpretation of PCG proved valuable for the rapid mass-screening of cardiovascular disease. It provides more objective and quantitative information than human auscultation, although it is still at a developmental stage because of the present technical limitations. The solution of these shortcomings should achieve an automated PCG analysis of high accuracy.
