In 20 newborn thoroughbred foals cardiovascular examinations were made on the heart rate and detailed auscultation of the cardiovascular murmurs, which were also recorded by phonocardiography, was conducted between birth and two weeks of age. A transient bradycardia, which was slower than the near-term fetal heart rate, was noted in neonates immediately after birth. Rapid and progressive increa...

Precordial and intracardiac phonocardiographic correlation was investigated in 28 cases with ventricular septal defect (VSD) to confirm the diagnostic value of intracardiac phonocardiography and to clarify the clinical as well as physiological significance of the point of maximum intensity (PMI) of the regurgitant systolic murmur of VSD. At the same time, the teleological use of catheterization...

In a survey of the Sheffield Region, Stuart-Harris, Twidle, and Clifton (1959) found that cor pulmonale was the commonest cause of heart failure resulting in admission to hospital. The investigation to be described was initiated when a patient in heart failure due to cor pulmonale was found to have a systolic murmur suggesting tricuspid incompetence which radiated down below the diaphragm into ...

Stable angina is a form of coronary artery disease. Its potential to progress requires the most appropriate treatment in order to reduce the incapacitating effect of an acute angina attack and to avoid long-term cardiovascular events. With or without revascularization, pharmacological treatment is an essential component of this treatment strategy, which also involves lifestyle and diet. Statins...

Phonocardiographic and pathological features of mitral porcine aortic heterograft valve failure are described in 1o patients with rheumatic valvular disease. Six had isolated mitralporcine aortic heterograft valve; 3 also had one in the aortic area; one had this in both mitral and tricuspid areas with an aortic ball valve prosthesis. Allpatients had systolic murmurs at the apex indicative of mi...
