The authors observe the contour and location of the U loop in normal, hypertension, aortic insufficiency and infarction.<br>(1) In normal cases, the horizontal U loop is located leftanteriorly with the small loop or V shape, and the left sagittal U loop is located anteroinferiorly with small loop. The U loop in frontal plane is located leftinferiorly with hookor γ type.<br>(2) In hypertension, the U loop in horizontal plane is dislocated from leftanteriorly to rightanteriorly. The contour of the U loop is γ or V shape and in cases with the T loop located rightanteriorly with clockwise inscription, the U loop is V shape with clockwise inscription. The authors call those U loop as the secondary U loop change.<br>(3) In aortic insufficiency, the U loop change in horizontal plane is similar to that in hypertension, but, in some cases the middle portion of the horizontal U loop is located rightanteriorly, the terminal portion remaining leftanteriorly. This characteristic type corresponds to the third type in hypertension and might be due to diastolic overloading.<br>(4) In some cases with hypertension and many cases with anterior or anterolateral infarction, the horizontal U loop is dislocated to the right or rightposteriorly or is shaped with round or ellipse. These changes of the U loop are called as the primary U loop change.<br>(5) The genesis of the U loop is discussed with those results.
