在完整心脏的心肌性能研究中,连续测量左心室间隔外侧直径提供了有用的信息。我们描述了一种将压电直径计放置在心室间隔的左心室心内膜上的技术。该技术简单且相对无创伤。它提供了一种在急性或慢性实验中评估室间隔横向尺寸的方法,并产生代表左心室瞬时室间隔横向尺寸的稳定信号。
In studies of myocardial performance of the intact heart, continuous measurement of the left ventricular septal-lateral diameter provides useful information. We describe a technique for placing a piezoelectric diameter gauge on the left ventricular endocardium of the intraventricular septum. This technique is simple and relatively atraumatic. It provides a way to evaluate septal-lateral dimension in either acute or chronic experiments and produces a stable signal that represents the instantaneous septal-lateral dimension of the left ventricle.
