中文摘要 | 本文研究的目的在探討滲液緊縮性包膜炎的心房膈運動情形及其機轉。 七位經臨床,心臟超碣波及心道管檢查,證實為滲液緊縮緎心包膜炎病患,皆給予經食道心臟超音波檢查,同時配合心電圖監視,以記錄及分析心房中膈運動的情形;其中四位同時接受經食道超音波及血流動力學檢查。結果顯示心房中膈運動有三種型態,分別是(1)正常(normal),即在心室收縮中,晚期及舒張初期,心房中膈往右心?方侗移動;在心室收縮早期及舒張末期,心房中膈往左心?方向移動。(2)心室收縮期,心房中膈隨吸氣迅速左心房方向移動(brisk inversion)。(3)心室收縮期,心房中膈持續性往左心房方向移動(sustained)。血流動力學研究顯示,心房中膈運動與心房間壓力差有關。 |
英文摘要 | Transesophageal echocardiography was performed in 7 patients with effusive-constrictive pericarditis to analyze atrial septal motion(ASM). In 3 patients, the ASM was found to be normal with atrial septum (AS) moving toward the right atrium from ventricular mid-systole to early-diastole and toward the left atrium from mid-diastole to early-systole. Respiration had little effect on the ASM. In 2 patients, a brisk inversion of ASM toward the left atrium at ventricular early-to-mid systole was noted during inspiration. In the other 2 jpatients, a sustained ASM toward the left atrium during ventricular systole was found. In 4 of these 7 patients, hemodynamic studies were performed simultaneously with the transesophageal echocardiography. The ASM reflected the pressure gradient between the left atrium (as measured by pulmonary arterial wedge pressure) and the right atrial pressure decreased markedly during inspiration. In conclusion, the ASM in lpatients with effusive-constrictive lpericarditis showed 3 patterns: normal, sustained systolic motion toward the left atrium and a brisk systolic displacement toward the left atrium during inspiration. The ASM reflects changes in the interatrial pressure gradient. |
