查询词典 conduction

本实验采用成年狗，以6极心导管电极从颈外静脉插至上腔静脉与右心房交界处，能记录到一个在心电图P波以前19—26毫秒的&P前波&。通过夹除窦房结和高血钾等实验证明，&P前波&可与P波分离而存在，并随窦房结夹除而消失。

No Ⅲ° atrioventricular conduction block happened, 9 patients developed right bundle branch block, and 2 patients showed junctional rhythm. Two patients with perimembranous extending outlet were repaired because of residual shunt(0.4cm,0.3cm) on the anterosuperior rim of defect. One patient with trivial residual shunt(0.15cm) on the posteroinferior rim of defect was found closed spontaneously six months later. Tricuspid valve was incised in 10 patients of VSD sextending outlet,8 patients vertical to the valve ring,2 patients parallel to the valve ring. Moderate tricuspid valve regurgitation was found in 1 patient, mild in 5 patients, trivial in 4 patients. No one aggravated. One patient complicated with pericardial effusion.

Objective To explore the prediction of bone-conduction of audiometric threshold in normal-hearing adults using multiple auditory steady-state response. Methods BC-ASSR and BC-A were recorded in 20 normal-hearing adults(10 males and 10 females). The response thresholds and the behavioral thresholds were compared at 0.5, 1.0, 2.0 and 4.0kHz to get the correlation and regression formulae.
