Study of Myocardial Inotropism and Chronotropism Based on Telemetering Heart Sound Signal;
在对心音信号进行进一步的处理之前，必须对噪声加以抑制。
Heart sound is one of the most important physiological signals and has been applied in the cardiac disease diagnose and the cardiac contractility evaluation because it can reflect cardiac inotropism and chronotropism.
心音是人体最重要的生理信号之一，能反映心脏的变时性和变力性，可应用于心血管疾病的诊断和心肌收缩能力的评估。
The strict synchrony between ECG signal and heart sound signal implys that heart sound signal can be used to study myocardial chronotropism.
而心音信号与心电信号之间存在严格同步关系的生理机制又提示可以利用心音信号来研究心肌的变时性。
Using K~+ selective microelectrode, H~+ electrode and oxygen electrode, the effects of Baogongteng-A on K~+, H~+, pO_2 and inotropism and chronotropism were observed concurrently in perfused rat heart.
本工作采用大鼠离体心脏灌流记录心率及心缩强度，同时应用氧电极、K~+选择性微电极以及H~+电极同步观察包甲素的作用并与乙酰胆碱作了某些比较。
