近年来,很多学者运用心导管检查,以研究和評价洋地黄对正常人和各种器质性心脏病病人的血液动力学的影响,积累了大量的資料。本文将比較肯定的研究結果,分別綜述如下。对正常心脏动力的影响以往学者长期以来均认为洋地黄对正常心脏有損。他們所持理由:(1)洋地黄作用于正常人或动物的心脏,可使其舒张期的紧张力增加,阻碍血流充分地进入心脏;(2)洋地黄有助正常心脏收縮力增强,使心脏容积减小,故每次心搏量相应减少;(3)洋地黄作
In recent years, many scholars use cardiac catheterization to study and evaluate the effect of digitalis on the hemodynamics of normal and various organic heart disease patients, and accumulated a great deal of data. This article will be more positive research results, respectively, are summarized below. Effects on Normal Cardiac Power Historically, digitalis has long considered digitalis detrimental to the normal heart. Their reason: (1) digitalis act on the heart of normal people or animals, can increase its diastolic tension, impede the full flow of blood into the heart; (2) digitalis helps normal heart contractility increased, so that Reduce the volume of the heart, so a corresponding reduction in stroke volume; (3) digitalis for
