Abstract
The application of "real time" spectrum analysis to left ventricular pressure during transient phenomena is described. Transient phenomena generated by the injection of drugs (norepinephrine-isoproterenol), anoxia and occlusion of aorta and carotids show sudden changes in the frequency of heart contraction. Propranolol stabilizes the heart rate in similar circumstances.
摘要
本文描述了“实时”频谱分析在短暂现象期间左心室压力方面的应用。由注射药物（去甲肾上腺素 - 异丙肾上腺素）、缺氧以及主动脉和颈动脉闭塞所产生的短暂现象显示出心脏收缩频率的突然变化。在类似情况下，普萘洛尔可使心率稳定。
