In cardiology, echocardiography is "ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic."[1]
There is about a ±15% variation in measuring the ejection fraction; the variability can be reduced with education of echocardiographers.[2]
Heart failure
Echocardiography measures the fractional shortening of the ventricle which can estimate the left ventricular ejection fraction in order to detect heart failure.[3][4][5]
Various parameters on echocardiogram can estimate left ventricular end diastolic pressure.[6]
Handheld echocardiography
Handheld echocardiography is an option.[7] may help.
"The rapid acquisition of images by skilled ultrasonographers who use PME yields accurate assessments of ejection fraction and some but not all cardiac structures in many patients". [8]
