In several such cases, skin affections were also present. Some suffered from acne vulgaris of the face with the usual comedones; others perspired profusely from the palms of the hands and the soles of the feet; others exhibited a bluish coloration of the nose and the ears. There is yet a third form of heart trouble, much rarer indeed than the forms already described, from which young girls sometimes suffer at the time of the menarche. It occurs in girls who just before the first appearance of menstruation have grown very rapidly, “shooting up to a great height.” They are not anæmic, nor do they appear “nervous;” but they are extremely thin, and they have grown enormously in height during the previous year. These individuals also, who in the previous course of their life have been free from heart trouble, now complain of cardiac distress. As in the cases previously described, they complain of severe palpitation, a feeling of fulness in the chest, shortness of breath on exertion, etc.; but the results of the objective examination are very different. The cardiac dulness is increased in area, especially in vertical extent, the apex-beat may be normal in position or displaced outwards, the impulse is always heaving, abnormally powerful and resistant, the heart-sounds, especially those of the left ventricle, are louder than usual, the aortic second sound accentuated, sometimes ringing, the carotids pulsate visibly. The radial pulse, the tension of which is abnormally high, can be compressed by the finger only with difficulty; sometimes it is jerky in character. The sphygmographic tracing shows a rapid and steep upstroke; in the downstroke, the predicrotic elevation is much larger than normal and also nearer the summit of the curve. Thus we see that all the signs of cardiac hypertrophy are present, hypertrophy, that is to say, of the left ventricle.
