I use the term cardiopathia uterina to denote the manifold cardiac disorders which occur in women as reflex processes excited by the physiological functions and the pathological disorders of the genital organs, and take the form of very various disturbances of the cardiac function. Every phase of the sexual life of women—that in which the reproductive organs attain complete development and menstruation first appears (the menarche); the commencement of sexual intercourse; pregnancy, parturition, and the puerperium; finally the retrogressive process at the climacteric age, of which the menopause is the outward manifestation—may give rise to the occurrence of such cardiac troubles. In order to explain these troubles as reflex in their nature, we must on the one hand recur to the anatomical changes in the uterus and its annexa that take place in every one of the above-mentioned phases of the sexual life; and on the other hand we must take into consideration the mental processes that accompany these anatomical changes, in order to estimate their influence upon the motor and sensory nerves of the heart (see the sections on the Menarche and the Menopause).
A certain predisposition to uterine cardiopathy exists in many individuals and in many families. This predisposition may be manifested in this way, that in women who at the time of the menarche have suffered from cardiac disorder, similar cardiac disorder is likely to recur at the time of the menopause, the symptoms of the recurrent attack being in most cases identical with those that occurred during the menarche. In the well-to-do and cultured circles of society, uterine cardiopathy is far more frequently encountered than among the working classes. Both unusually early and unusually late commencement of menstruation tend to favor the occurrence of uterine cardiopathy. The most valuable therapeutic measures that we can employ to combat these disorders are suitable dietetic and hygienic regulations, in association with favorable mental influences.
Diseases of the female reproductive organs, including simple functional disturbances, are very frequently accompanied—far more frequently than has hitherto been supposed—by cardiac disorders. But whereas in some cases these cardiac disorders are directly dependent upon the disease of the genital organs; in other cases no such etiological relationship can be shown to exist, and the association must, therefore, be regarded as fortuitous.
In cases of the former kind, the dependence of the cardiac disorder upon the disease of the genital organs is very variable in its nature.
Reflex manifestations on the part of the nervous system may be aroused by pathological changes in the genital organs, in a manner similar to that discussed in other parts of this work in regard to the cardiac troubles that are liable to occur during the menarche and the menopause; such cardiac disorders are indeed excited especially by changes in the ovaries, by disturbances of menstrual activity, by suppression of the menses—as manifestations, that is to say, of the menstrual reflex. The cardiac disorder most commonly takes the form of tachycardiac paroxysms, recurring periodically, either in association with the menstrual flow, or, if this is in abeyance, at the times at which it ought to appear. We must assume in these cases that the local stimuli aroused by the pathological changes in the uterus and the ovaries have a reflex influence upon the cardiac nerves, by means of which the heart’s action is increased in frequency, without inquiring more particularly whether the reflex influence is effective by inhibiting the normal action of the vagus, or by stimulating the sympathetic, or, perhaps, by a combination of these factors. Much more rarely do we notice, in association with disorders of the reproductive system, a reflex decrease in the frequency of the heart’s action, this effect being explicable in the same manner as the well-known experiment of Golz, in which, if the abdomen of a frog be laid bare, and the intestine be struck sharply with the handle of a scalpel, the heart will stand still in diastole with all the phenomena of vagus inhibition.
In another group of diseases of the genital organs, the disturbances of cardiac activity may be brought about by pressure which, in consequence of the morbid processes in the reproductive organs, is exercised upon individual nerves or upon an entire nerve plexus. Tumefied and prolapsed ovaries, an enlarged and misplaced uterus, inflammatory nodules and hyperplasias of the intrapelvic connective tissue, contractile processes in the parametric connective tissue,[[40]] tumors of the uterus whether intramural or in the interior of that organ, ovarian tumors, prolapse of the uterus, and intrapelvic peritoneal adhesions resulting from inflammatory processes—these are the principal conditions liable to occasion reflex cardiac disorder; but certain tissue changes, such as endometritis, erosions (chronic cervical catarrh), and ulcerations of the genital passages, with or without exposure of nerve-endings, are also competent to produce the same effect. Here the sympathetic nervous system constitutes the channel by means of which the stimuli affecting the nerves of the genital organs are conveyed to the central nervous system, and by means of which also the reflex manifestations of this stimulation are produced, taking the form, partly of disorder of the cardiac action, of palpitation of the heart and paroxysmal tachycardia, and partly of pains in the cardiac region and disturbances along the course of the great vessels.
Further, in cases of long-continued disease of the female genital organs associated with severe hæmorrhage and in some cases fluor albus, nutrition in general and hæmotopoiesis may be seriously affected, and disturbances of cardiac activity may result, as, for instance, is frequently witnessed in chloro-anæmic states. In such cases we have palpitation of the heart, both subjective and objective, a weak and compressible pulse, often irregularity of the heart’s action, singularly clear heart sounds, often, however, systolic murmurs at various orifices, increased frequency of heart and respiration to a disproportionate degree on slight exertion, strong pulsation of the carotids, and slight œdema of the ankles.
Often, however, the disturbance of cardiac activity is dependent also upon degenerative processes in the myocardium, upon fatty degeneration and the consequent dilatation of the cavities, this degeneration being a consequence of the growth of a uterine tumor and especially of uterine myomata, or resulting from some constitutional disorder which is itself dependent upon the affection of the genital organs. In such cases the signs of degeneration of the heart are very striking: weakening of the cardiac impulse, notable faintness of the sounds of the heart, occasionally reduplication of the second sound, a galloping rhythm, while percussion shows the existence of considerable dilatation of the left, and still more frequently of the right ventricle; in many cases also we have angina pectoris, passive hyperæmia of the lungs, the mucous membranes, and the extremities; and sudden death sometimes ensues.
No less important are the mental influences exercised by diseases of the genital organs in which operation is proposed or actually performed, also by long-lasting diseases of the reproductive organs and by the disturbances these diseases produce in the reproductive functions, more especially in relation to copulation and the actual process of reproduction. In this way cardiac neuroses of various kinds may be induced.
Finally, cases have come under my notice in which the cardiac trouble was not the direct result of the disease of the genital organs, but was a consequence of the therapeutic measures employed for the relief of the latter; and in this connection I must regard as especially blameworthy, in addition to intra-uterine manipulations, such as sounding and cauterization, the modern practice of gynecological massage.
