Frances Bekele,Wilbert Phillips-Morahy, commercialized as Acoustic Quantification (AQ), has been shown to provide quantitative analysis of LA size and function. This chapter focuses on invasive and noninvasive measurements of LA function and applications of AQ for the assessment of LA performance and the future potential of AQ in clin

Advances in Plant & Microbial Biotechnologyllows for rapid visualization of the beating heart. To exploit this capability, both the sonographer and the cardiologist interpreting the ultrasound images require extensive training. Performing a proper ultrasound examination requires that the sonographer be knowledgeable on the correct placement

These measurements can then be used to calculate load-dependent parameters of systolic performance such as ejection fraction and stroke volume in real-time. In addition, it is possible to generate load-independent parameters of sy

Breeding of Pearl Millet (, (L.) R. Br.), in 1984. In his study of 188 patients with heart failure, 36% of the patients had normal or near normal left ventricular (LV) systolic function, with ejection fractions of 0.45 or greater. Echocardiographic findings in these patients demonstrated an abnormally low left atrial emptying index which s
