Theaction of the heart at the time was extremely rapid and interesting, and to me exceptional, phenomenon lasted for INTRODUCTORY 33 several minutes, indeed so long as the rapidity of cardiac actionendured. When at length her pulse grew more quiet the musicalmurmur became inaudible and did not reappear. This patientwas seen by me in Septe^nber, 1900, after a lapse of more than ayear from her last visit, and although I diligently sought for thetwanging sound and any signs of cardiac disease, I failed to detectany abnormality. The patient reported herself as in much betterhealth and less excitable, being but rarely annoyed by her formersymptoms, and indeed appeared not the least disturbed by Fig. 12.—Heart of a Buffalo aberrant chordfe tendinee in left ventricle. The only explanation that has seemed to account for this re-markable phenomenon is that the musical murmur was due to thevibration of one of the so-called aberrant cords (Fig. 12) or mod- 34 DISEASES OF THE HEART ernlor hands, desoribcJ l)v H.

They have nothing to do with the chordnetendina?, and unless care is taken, may be cut in the opening ofthe ventricle and thus escape detection. Although most frequentin the left, they have been found in the right ventricle, and thereare instances of such a band passing from the valve of the fora-men ovale into the cavity of the l
