TL;DR: The differential diagnosis of ventricular septal perforations should be strongly considered when a patient with an acute myocardial infarction suddenly develops a blowing systolic murmur along the lower left sternal border.

TL;DR: An ontogenetic theory is proposed to explain congenital truncoconal malformations as a consequence of developmental alterations of the conoventricular flange, the truncOConal ridges, and the primordia of the aortic and pulmonary cusps.

TL;DR: The presence of C-reactive protein in the blood of patients with congestive heart failure limits the application of C.reactiveprotein determinations as a measure of rheumatic activity in acute Rheumatic fever and in chronic rhematic heart disease and as a measures of necrosis in acute myocardial infarction.

TL;DR: The present report, based on observations made on normal individuals and patients with cough syncope, suggests a more acceptable mechanism for this type of fainting.

TL;DR: The pattern of incomplete right bundle branch block has been observed to emerge from that of right ventricular hypertrophy after closure of the atrial defect, and it is suggested that the pattern of right bundles branch block encountered in atrial septal defect represents the normal cardiac vectors, not Bundle branch block.

TL;DR: Results suggest that venous tone is subject to the same forces that act on arterial or arteriolar tone as well as other factors related to sympathetic nerve activity.

TL;DR: Cardiorespiratory function studies showed hyperventilation, anoxemia, and pulmonary arterial hypertension with increased blood flow, and supportive treatment with noradrenaline, oxygen, and adrenocorticotrophin resulted in complete recovery.

TL;DR: Complicated multiphasic differential complexes of a low voltage are demonstrated locally in the anatomic sinus nodal region and in the atrioventricular node, and a theory is postulated concerning the origin and the conduction of the activation in the auricle of the dog.

TL;DR: In this article, results of left heart catheterization in two normal individuals and 125 patients with rheumatic heart disease were presented, and the normal pressure curves were described. But no pressure gradients exist across a normal mitral or aortic valve.

TL;DR: Pectus excavatum is a congenital thoracic deformity which, in moderate and severe cases, may result in profound disturbances of cardiorespiratory physiology and can be corrected satisfactorily by operation with good physiologic and cosmetic results.

TL;DR: Flow at critical velocities produced changes in the form of channels lined with a deformable silicone, with the development of structures superficially resembling those seen in blood vessels, with effects attributed to the operation of mechanical forces.

TL;DR: Isuprel (isopropyl norepinephrine) was found to be the most useful drug in this series, regardless of the underlying mechanism producing attacks, and the prognosis of symptomatic complete heart block is generally poor.

TL;DR: The principle of arterial oscillometry has been applied to the cervical vessels by connecting a cuff placed around the neck to a recording differential manometer, essentially pneumatic without recourse to electronics, which shows features almost identical to the carotid sphygmograms.

TL;DR: The phonocardiogram allows conclusions about the pressure increase in the left auricle which in turn is closely related to the degree of mitral stenosis and allows unlimited control examinations for later evaluation of the increase of exercise tolerance after mitral valvotomy.

TL;DR: Two methods for calculating the amplitude characteristic of the high-frequency BCG, the difference in movement of subject and BCG taken into account, are compared and discussed.

TL;DR: Thirty-four patients with persistent and unexplained RS-T segment and T-wave changes were seen at the Madison Veterans Administration Hospital between May, 1952, and May, 1954 and it was demonstrated that these patients had some form of psychiatric or emotional disorder.

TL;DR: A direct naturetic and diuretic effect ofDigoxin on the kidney was demonstrated and a comparison of the renal action of Digoxin and mercurial diuretics was discussed.

TL;DR: A case of progressive muscular dystrophy with cardiomegaly, congestive heart failure, and sudden death is presented and some of the interesting clinical and electrocardiographic features are discussed.

TL;DR: The case history of an apparently healthy young man who died following a nonpenetrating trauma to the chest from a steering-wheel accident is reported and a ruptured interventricular septum was found.

TL;DR: Moderate exercise (walking on the treadmill and stepping up and down) produced statistically significant changes of most electrocardiographic items (both conventional and spatial vectors) in ninety-one middle-aged normal men.

TL;DR: The technique, premedication, and approach for left heart catheterization have been presented, and problems pertaining to left atrial puncture have been described, and suggestions made.

TL;DR: Three cases with bilateral constriction at the point of bifurcation of the main pulmonary artery are described and the suggested nomenclature should be adopted for describing this entity.

TL;DR: Arteriovenous fistulas of the heart do not appreciably shorten the life span, and their diagnosis during life is important principally to avoid confusion with more serious heart disease.

TL;DR: The purpose of this study was to measure the degree to which the background noise levels actually present in hospital wards and examining rooms can impair one's ability to hear heart murmurs through the stethoscope.
