Arguments in Favour of the Theory of Dilatation of the Heart as the Cause of Cardiac Hæmic Murmurs, and of the Appendix of the Left Auricle Being the Primary Seat of This Murmur

The valvular lesions which but a few years ago were almost the only recognised lesions of the heart, which seemed so difficult to diagnose, and to threaten life so seriously and mysteriously, are nowadays readily discovered, differentiated, and their influence as mechanical hindrances discounted. All the interest and the mystery is now transferred to the state of the cardiac muscle and its nervous relations. And of all the problems we are thus brought to face, none is so simple, and few more important, than the actual condition of the chlorotic heart, which has so long been misunderstood.
