Point-of-care transthoracic echocardiogram subcostal short-axis views. a Short-axis view of the left ventricle at the level of the papillary muscles reveals the left ventricle initially in diastole, b followed by mid-systole, and c in late systole. Symmetric contraction of the left ventricle is appreciated until near obliteration of the left ventricle cavity in late systole, which is indicative of a hyperdynamic and under-filled left ventricle
