What are the normal values of each chamber of the heart?

Normal values for each chamber of the heart are 23-38mm for the left atrium, 30-40mm for the right atrium, 35-50mm for the left ventricle and 10-25mm for the right ventricle.

Usually the heart is divided into 4 chambers, of which the upper two are atria, divided into left atrium and right atrium by atrial septum, and the lower two are ventricles, divided into left ventricle and right ventricle by ventricular septum. In general, the normal range of left atrial diameter at end-systole is 23-38mm, the normal range of right atrial diameter at end-diastole is 30-40mm, the normal value of left ventricular diameter at end-diastole is 35-50mm, and the normal value of right ventricular diameter at end-diastole is 10-25
