These myocardial changes are sometimes associated with chronic pericarditis and chronic endocarditis, and may accompany or follow valvular disease of the heart. Failure of compensation in valvular disease and dilatation of the heart are sequences which occur sooner or later. The heart frequently becomes more rapid, not only with exertion and change of position to the erect, but even after eating.
On the other hand, many instances of valvular lesions may be found during a life-insurance examination, or are discovered by the physician making a general physical examination for an indefinable general disturbance or for local symptoms. without the patient ever having known that he had a damaged heart.
Such irregularity perhaps most frequently occurs with valvular disease, especially mitral stenosis and in the muscular degenerations of senility, as fibrosis. Atropin has been used to differentiate functional heart block from that produced by a lesion. Jour. Med. In the first the heart block is induced by digitalis. This was entirely removed by atropin.
The heart is one of the greatest sufferers from alcohol. Quoting again from Dr. Richardson: "The membranous structures which envelope and line the organ are changed in quality, are thickened, rendered cartilaginous and even calcareous or bony. Then the valves, which are made up of folds of membrane, lose their suppleness, and what is called valvular disease is permanently established.
Every here and there were curious shell-fish, some creeping like snails with their heavy houses upon their backs, others were oyster and mussel like, anchored and lying with their valvular shells half open; while a couple of yards away lay one monster about two feet long, a bivalve with ponderous shells, whose edges were waved in three folds, and a glance inside whose opening showed a lining of the most delicate pinky tint.
#Intracranial aneurysm# involves the internal carotid and its branches, or the basilar artery, and appears to be more frequently associated with syphilis and with valvular disease of the heart than are external aneurysms. It gives rise to symptoms similar to those of other intracranial tumours, and there is sometimes a loud murmur. It usually proves fatal by rupture, and intracranial hæmorrhage.
The "breath-band" advocates hold that the glottic stroke is the key to correct laryngeal action. As a rule they instruct their pupils to attack every tone, throughout all their practising, with the stroke of the glottis. In the course of time the automatic valvular action is supposed to become so well established that the singer can dispense with the glottic stroke in public performance.
This valvular protrusion was easily depressed by the finger. St. Martin suffered little pain except from the depression of the skin. He took his food and drink like any healthy person, and for eleven years remained under Dr. Beaumont's own care in the Doctor's house as a servant. During this time were performed the experiments on digestion which are so well known. St.
Auricular fibrillation may occur in hearts which are suffering from valvular lesions, especially mitral stenosis, and may occur in syphilitic hearts, in various sclerotic conditions of the heart, and in hyperthyroidism. Though disputed, it seems probable that fibrillation may be caused by the excessive use of tea, coffee and tobacco.
Like any other muscular tissue, the heart hypertrophies when it has more work to do, provided this work is gradually increased and the heart is not strained by sudden exertion. To hypertrophy properly the heart must go into training. This training is necessary in valvular lesions after acute endocarditis or myocarditis, and is the reason that the return to work must be so carefully graduated.
