JOURNAL FREE ACCESSAn attempt was made in this study to correlate the phonocardiographic features with clinical findings in 105 cases of aortic regurgitation. The basic configuration of the aortic diastolic murmur is holodiastolic in nature and has a crescendo-decrescendo figure. Its time of accentuation, the grade of decreasing intensity and the loudness have good correlations with clinical findings of aortic regurgitation. The rapid filling and atriosystole frequently influence upon the configuration of the murmur. The “Q-1” interval shows the prolongation in severe cases, and there occurrs the “prediastolic murmur” in some instances.View full abstractDownload PDF (15372K) -

JOURNAL FREE ACCESSRepeated phonocardiographic examinations were made on 65 cases with initial attack of rheumatic fever. A total of 52 patients having cardiac manifestation were served as consecutive study. Authors present the phonocardiographic features in the early stage of rheumatic carditis correlating with the activity of the disease; in most instances significant murmurs, gallop rhythm and abnormal splitting of pulmonic second sound are coincident in acute phase. Among significant murmurs apical mid-diastolic murmur displays its reversibility. The E/M at apex or ratio of the duration of electrical systole (QT-interval) to that of mechanical systole (I-II interval in apical Medium PCG) varies with the degree of rheumatic activity. Increasing value of this ratio is parallel with rheumatic process. From these results presence of rheumatic activity would cause flabby or feeble state of myocardium which may also be an important factor in generating significant murmurs as well as actual “valvulitis”.View full abstractDownload PDF (6121K) -

JOURNAL FREE ACCESSTo elucidate the mechanism of the cardiac lesions due to thiamine deficiency, authors have been carrying on studies on the cardiac lesions in pure thiamine deficient rats.
In this paper, the general progress, electrocardiograms and histological findings observed on control normal rats and on thiamine deficient rats are reported.View full abstractDownload PDF (13200K) -
Effect of the Electrical Stimulation of Splanchnic, Vagal and Other Somatic Nerves and of the Occlusion of Carotid Arteries on the Renal CirculationJugoro TAKEUCHI, Eiichi UCHIDA, Shosaku NAKAYAMA, Tadanao TAKEDA, Shig ...1961 Volume 2 Issue 1 Pages 65-76

JOURNAL FREE ACCESSIn order to investigate the nervous control of the renal circulation, the renal blood flow was measured by electromagnetic flow meter during the stimulation of the distal cut ends of the splanchnic nerves and the vagal nerve. In addition, the alterations of renal blood flow were observed on carotid occlusion and on stimulation of the proximal end of the divided femoral, sciatic and cervical vagal nerves. The stimulation of the greater and lesser splanchnic nerves produced constriction of renal vessels but the stimulation of the least splanchnic nerve had no effect. The effect of stimulation of the distal end of the vagal nerve to the renal vessels remained unestablished. Carotid occlusion did not influence the renal blood flow. The stimulation of the proximal end of the divided femoral or sciatic nerve may have produced renal vasoconstriction. By the stimulation of the proximal end of the divided vagal nerve, the renal vessels showed various responses with no relation to the alteration in blood pressure. It is a matter of interest that renal vasodilatation may take place in response to vagal afferent stimuli.View full abstractDownload PDF (7894K) -

JOURNAL FREE ACCESSIn an attempt to elucidate the mechanism of the systemic hypotension produced by the rapid intravenous injection of 20percent saline, experiments were made using the intracoronary injection technique and transeptal left atrial puncture in a total of 25 dogs. Accompanying apnea and bradycardia were considered to be due to the pulmonary reflex via the vagus. Scrutiny of systemic hypotension produced after injection of hypertonic saline into varying cardiovascular chambers showed that the injection into the left side of the heart also resulted in the same degree of hypotension as that of the right side, and that pressure fall was separated into early and late dips, about which the genesis was discussed and the former was attributed to the coronary effect. Electrocardiographic analysis revealed that the ST and T changes were the proof of the arrival of saline at the coronary circuit and their mechanisms were mentioned. From these results the authors emphasized the possible role of coronary effect by the agent and suggested the transient myocardial failure in the production of systemic hypotension.View full abstractDownload PDF (11747K) -

JOURNAL FREE ACCESSRecent studies on the electrocardiographic patterns in cases with cerebrovascular accidents have shown that a neural factor might be responsible for the abnormalities in the electrocardiograms, but we have as yet very little clinical information in cases with neurosurgical lesions. The purposes of this presentation are to describe the pre- and postoperative electrocardiographic patterns and to discuss the possible causes inducing abnormalities in the postoperative electrocardiograms.
Evidence is presented in 323 neurosurgical cases that the high incidence of abnormal electrocardiographic patterns, especially flat or inverted T waves and S-T segments depression, are exhibited postoperatively in cases with supratentorial lesions, especially with craniopharyngioma, hypophyseal adenoma and other sellar tumors and with the fronto-temporal lobe tumors.
From the results of this study, it may be suggested that in cases with neurosurgical lesions, electrocardiograms may also be affected by a neural factor from surgical damage to the parapituitary areas of the central nervous system.View full abstractDownload PDF (17195K) -
Part III. Representation of the Electric FieldMitsumasa SATO1961 Volume 2 Issue 1 Pages 112-118
Published: 1961
Released on J-STAGE: October 26, 2009
JOURNAL FREE ACCESSDifferent from the previous 4 chapters dealing with one electric field, the present chapter concerns a set of the fields. The structure of the set of electric fields and its vectorial nature are discussed by refering to its “homomorphic image” or “representation.” Here the widely accepted method in practical electrocardiography, the “mean spatial vector” method, is criticized from this point of view.
This chapter may be summarized by a catchy expression ELECTRIC FIELD IS VECTOR, corresponding to the expression in Part I that ELECTROCARDIOGRAM IS VECTOR.View full abstractDownload PDF (3755K) -

JOURNAL FREE ACCESSTHE technique of resection and transplantation of the thoracic aorta, especially of the ascending aorta or the aortic arch has been behind the time because of its influence to the heart, problems concerning the cerebral circulation, spinal cord damages and difficulties of the technique itself. Since DeBakey et al. reported operative methods for resection of aneurysm of the ascending aorta or the aortic arch with temporary bypass graft or with extracorporeal circulation, several cases of this kind of operation have been reported.
Recently, 2 cases with aneurysms of the ascending aorta and the aortic arch have been operated with the use of prosthesis in our hospital and the cases will be herewith presented.View full abstractDownload PDF (6590K)
