JOURNAL FREE ACCESSUnusual, hitherto undescribed form of, diastolic heart beat was reported in a case of tense pericardial effusion and in another case of seroconstrictive pericarditis. It consists of large and sharp early diastolic thrust, the peak of which conincides in time with the protodiastolic extrasound (pericardial knock). The mechanism and the diagnostic significance were discussed. Failure to recognize this diastolic heart beat in most cases of pericardial effusion or seroconstrictive (effusive-constrictive) pericarditis may be due to the absolute faintness of the precordial movement in these conditions. In addition, inspiratory widening of the split second heart sound due to the shortened electromechanical systole was described in a case of tense pericardial effusion without constrictionView full abstractDownload PDF (5833K) -

JOURNAL FREE ACCESSIt has been difficult to obtain satisfactory records of the tricuspid ultrasound curve in healthy subjects, possibly because of some anatomical reasons. In the present study, attempts were made to overcome the above difficulties and to obtain satisfactory records of the tricuspid ultrasound curve in healthy subjects.
1. To study the tricuspid ultrasound curve in healthy subjects, a special equipment was devised.
2. The tricuspid ultrasound curve was recorded with this equipment in about half the healthy subjects examined.
3. In detecting the tricuspid valve the ultrasound beam should be sent into the chest medially 20°-40° from anterior-posteriorly through the vicinity of the left sternal edge in the third and/or fourth intercostal space.
4. The normal ultrasound curve of the tricuspid valve shows a 2-peaked configuration in a cardiac cycle as that of the mitral anterior cusp. The structure detected is concluded to be the anterior cusp on the basis of the direction of motion.
5. The amplitude of the normal tricuspid ultrasound curve and the "speed" calculated from the curve are similar to those of the mitral valve.
6. The "speed" of diastolic descent of the tricuspid ultrasound curve was 163mm./sec. or more in 20 cases measured in the present study.View full abstractDownload PDF (2422K) -

JOURNAL FREE ACCESSThe most characteristic findings of QRS waves of the spatial velocity ECG in atrial septal defect are that the velocity increased markedly after the initiation of the terminal delay. The peak velocity in the terminal delay and the velocities at the beginning portions of the terminal delay showed positive correlations with pulmonary artery and right ventricular pressures. Mean values of the pulmonary artery and the right ventricular pressures were significantly higher in the group with higher peak velocity in the terminal delay than in the group with lower peak velocity in the terminal delay. The durations of the terminal delays showed significant negative correlations with the pulmonary artery and the right ventricular pressures. Using only 2 parameters concerning the terminal delay of QRS waves of the spatial velocity ECG, namely the peak velocity in the terminal delay and the duration of terminal delay, 93% of the normal subjects, 100% of the usual type of the complete right bundle branch block and 95% of atrial septal defect were differentiated each other.View full abstractDownload PDF (589K) -
An Evidence Suggesting Association of Myocardial Abnormality with Chronic Alcoholism in 107 Japanese Patients Admitted to a Psychiatric WardTadashi KOIDE, Kikuo MACHIDA, Atsuo NAKANISHI, Katsuhiko OZEKI, Saburo ...1972 Volume 13 Issue 5 Pages 418-427

JOURNAL FREE ACCESSThe incidence of cardiac abnormalities was studied in 107 cases with chronic alcoholism, admitted to a psychiatric ward. More than half of them adhered to drink Japanese sake almost exclusively.
Either palpitation or shortness of breath was seen in 49 cases, cardiothoracic ratio was more than 0.50 in 15 of the 78 cases examined, and abnormal ECG was obtained in 65 of the 103 cases.
Among ECG abnormalities, broad and tall PII, high RV5, high T in leads V2 and V3 and QT prolongation were the most frequent. Various arrhythmias and conduction disturbances were also seen.
The clinical picture suggested more than incidental association of diffuse myocardial involvement with chronic alcoholism.View full abstractDownload PDF (1017K) -

JOURNAL FREE ACCESSCardiovascular (CV) reactivity to norepinephrine (NE) after cocainization, and to methoxamine was determined in spontaneously hypertensive rats (SHR), and in rats made hypertensive by clipping the renal artery and contralateral nephrectomy, or by the administration of deoxycorticosterone and salt. Cocaine inhibits the uptake of NE at the nerve terminals. Methoxamine is a sympathomimetic amine, not taken up by the nerve endings. The full dose-response curves were obtained without anesthesia after pithing, decerebration, and vagotomy. CV reactivity to NE was essentially unchanged after cocainization in the 3 types of hypertension. Reactivity to methoxamine was also unchanged in hypertension. The results indicate that neither differences in the mechanism of uptake nor sensitivity of the receptor sites is responsible for the elevated blood pressure (BP) in these types of hypertension. NE must be available in a larger amount at the receptor sites in the CV system to maintain the higher BP.View full abstractDownload PDF (397K) -

JOURNAL FREE ACCESSThe selective administration of dopamine, norepinephrine, epinephrine and isoproterenol, into the coronary sinus region of the dog heart produced so-called coronary sinus rhythm, indicating the appearance of deep inverted P waves and frequently accompanied by an acceleration of pacemaker activity of the coronary sinus region. These effects of catecholamines were not influenced by atropine and tetrodotoxin but were blocked by propranolol. The coronary sinus rhythm was easily produced by suppression of SA nodal pacemaker activity. Coronary sinus rhythm may be readily elicited if the coronary sinus area is excited by adrenergic stimuli or if the SA node is suppressed by cholinergic excitation.View full abstractDownload PDF (354K) -

JOURNAL FREE ACCESSHemodynamic effects of propranolol (0.5mg./Kg.) and subsequent carotid occlusion were investigated in 12 pentobarbital anesthetized intact dogs, including the measurement of both ventricular volumes by thermodilution method. The role of β-sympathetic nerve during pentobarbital anesthesia is remarkable judging from the changes induced by propranolol; that is, decreased cardiac output (3.69 to 2.87L./min.) and heart rate (186.6 to 138.7beats/min.), and increased left ventricular end-diastolic volume (3.28 to 4.03ml./Kg.) and end-diastolic pressure (4.0 to 10.9 mm.Hg) without increase of left ventricular stroke work, reflecting the negative inotropism of the drug. Subsequent carotid occlusion increased heart rate and myocardial contractility with the considerable vasoconstriction, that is, normalized mean circumferential shortening rate as a velocity of contraction of muscle fiber, and end-diastolic volume as a ventricular preload did not change while ventricular peak force as an afterload increased. The author concludes that the inotropic effect of carotid occlusion is mediated by so-called homeometric regulation together with β-sympathetic nerve activity.View full abstractDownload PDF (586K) -

JOURNAL FREE ACCESSTwo aged cases of mitral insufficiency due to ruptured chordae tendineae were reported. These cases had no past history of rheumatic fever and bacterial endocarditis. At autopsy, mitral insufficiency was explained by spontaneous rupture of chordae tendineae. Histologically, the ruptured chordae tendineae showed degenerative changes of connective tissue by aging process, which were suspected as one of the etiology among cases of spontaneous rupture.View full abstractDownload PDF (2375K) -

JOURNAL FREE ACCESSA case is presented in which a broken fragment of central venous pressure catheter remained in the right heart cavity with a short distal portion in the inferior caval vein was successfully removed with use of an endo-myocardial bioptome inserted from the saphenous vein. The less traumatic surgical methods for removal of intracardiac or intravascular foreign bodies are discussed.View full abstractDownload PDF (1085K)
