    page Oscillations similar to those, characterising complete irregularity of the heart in man are found experimentally when the auricle is fibrillating, and these oscillations are produced in the auricle as a result of the fibrillation . . . . . . 334 The electrocardiographic curves compared in more detail .. 337 The radial curves compared . . . . . . . . . . 330 The venous curves and their comparison . . . . . . . . 340 A summary of the comparison instituted between the records ob- tained in complete irregularity of the heart in man, and in experimental auricular fibrillation . . . . . . . . 345 AURICULAR FIBRILLATION AS A CLINICAL ENTITY . . .. .. .. 346 AURICULAR FIBRILLATION AND HEART-BLOCK ; THE ACTION OF DIGITALIS . . . . . . . . . . . . . . . . 340 THE CAUSE OF THE ONSET AND DURATION OF AURICULAR FIBRILLATION 353 AURICULAR FIBRILLATION AND VENTRICULAR EXTRASYSTOLES .. 356 CERTAIN CONDITIONS DIFFERENTIATED . . . . . . . . . 357 Cases in which the ventricidar form of venous pulse occurs, but in which either auricular fibrillation is absent or in which the evidence is insufficient to justify us in assuming its presence . . . . . . . . . . . . . . . . 357 True nodal rhythm' is a rare affection and gives rise to a clinical picture entirely at variance with that of the disorderly action of the heart hitherto considered. . .. .. .. 300 CHIEF CONCLUSIONS .. .. . . .. .. . . . . 368 BIBLIOGRAPHY .. .. .. .. . . .. . 360 Historical and introductory. In the following pages an account of a specific clinical condition, characterised in the great majority of cases by complete irregularity of the arterial ])ulse and by an absence of all signs of the normal auricular contraction, is given. It will be shown that the type of irregularity, which is one of the chief features of the condition, is the commonest persistent irregularity exhibited by the human heart, constituting as it does approximately 50 per cent, of all such cases ; and it will be demonstrated that the disturbance of cardiac rhythm is to be sought in the auricle and attributed to temporary or permanent inco-ordination of the musculature of that chamber.
