THE CAUSES OF RENAL PAIN 19 push the apex aside and backwards; a portion of the rightventricle wall representing the apex. In such a case the apicalcardiogram may show the characteristics of a mid-precordialcardiogram, or a combination, in varying degree, of the twocardiograms. In cases where the tension in the aorta is low, the,cardiogram may consist of an abrupt rise and fall; while incases where the tension is high, or the aorta inelastic, or theaortic orifice obstructed, the cardiogram may show slowly risingand falling lines, either straight or notched. In cases wherethere is a decided mitral regurgitation, the leak of blood escap-ing in jerks may cause a rapidly intermitting rise and fall ofpressure in the aorta and consequent notches and waves in thecrest of the cardiogram. Finally when the apex beat is powerful and is limited to asmall point in an intercostal space the violent blow which itgives the receiver may cause many secondary waves due to theelasticity of the instrument.
