门电路平衡血池显象法可以重复测定静息和运动时左心室容量和喷血分数(LYEF),其测定不以假设的几何图形为根据,是一种不影响左室功能或周围血管阻力的非侵入性检查方法。本文用这种新的血池闪烁显象法研究正常人和冠心病患者运动引起左心室容量和压力/容量(P/V)指数的变化,评价左室收缩末期容量(LVESV)和P/V 指数对检测冠心病患者运动诱发左室功能不全的敏感性。病例和方法:46例分成3组。A 组13例,男性10例,女性3例,平均年龄34.2岁,均无心脏病的证据。B 组9例,男性6例,女性3例,平均年龄
The portal balance BALP can be used to repeatedly measure left ventricular volume and ejection fraction (LYEF) at rest and during exercise, and is not based on a hypothetical geometry and does not affect left ventricular function or peripheral vascular resistance Non-invasive inspection methods. In this study, the changes of left ventricular volume and pressure / volume index (P / V) induced by exercise in normal subjects and patients with coronary heart disease were studied by this new blood bank flicker imaging method. The left ventricular end-systolic volume (LVESV) and P / V Index for the detection of exercise-induced left ventricular dysfunction in patients with coronary heart disease sensitivity. Cases and methods: 46 cases were divided into 3 groups. A group of 13 patients, 10 males and 3 females, mean age 34.2 years old, no evidence of heart disease. Group B 9 cases, 6 males and 3 females, the average age
