title: [Assessment of early pregnancy detection with sphygmogram of smooth pulse].
abstract: In order to assess the clinical availability of early pregnancy detection with Sphygmogram of smooth pulse, pulse pictures and endometrial tissues were simultaneously examined respectively with sphygmograph and pathological method in 205 cases of clinically diagnosed early pregnancy. Among them, 196 cases were pathologically confirmed as early pregnancy, 192 displayed smooth pulse on the Shygmogram. This shows the precision of sphygmogram of smooth pulse in detecting early pregnancy was 97.6%, its sensitivity 97.9%, Jordan index 0.868, specificity 88.9%, and misdiagnosis 11.1%. Though its specificity was not quite satisfactory, sphygmogram of smooth pulse has proved to be a sensitive index with high precision and easy management. Therefore, it is well worth to be popularized in China.
