In cardiology, echocardiography is "ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic."[1]
Heart failure
Echocardiography measures the fractional shortening of the ventricle which can estimate the left ventricular ejection fraction in order to detect heart failure.[2][3][4]
Various parameters on echocardiogram can estimate left ventricular end diastolic pressure.[5]
Handheld echocardiography
Handheld echocardiography is an option.[6] 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". [7]
