Abstract
|
|
|
Background :
@EN Recently intracardiac blood flow can be visualized by the development of color Doppler echocardiography, but the analytical studies on the intra-left ventricular flow are rare The analytical description of intraventricular flow is not only a
basis
of hemodynamic study but can be useful in illuminating the pathogenesis of LV thrombus formation and modelling artificial heart.
@ES Methods and Result :
@ENWe recorded NTSC analog signals of LV color Doppler M-mode echocardiogram and input these data into IBM personal computer by digital color image grabber, After filtering and processing these data. We get isovelocity lines of LV flow. We draw
LV
flow
velocity lines with time and location axis and be able to demonstrate the peak velocity point and intracardiac blood flow acceleration.
@ES Conclusion :
@EN We digitized LV color M-mode and drew normal intra LV flow We hope this method can be useful in describing intra-LV flow of hart disease.
