OBJECTIVE To evaluate new echocardiographic modes in the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC). DESIGN Prospective observational study. SETTING University Hospital. SUBJECTS 15 patients with ARVC and a control group of 25 healthy subjects. METHODS Transthoracic echocardiography included cross sectional measurements of(More)
AIMS Mitral atrioventricular plane displacement (AVPD) provides information about left ventricular systolic function. M-mode of systolic annulus amplitude or tissue Doppler imaging of systolic annulus velocity are the current methods of evaluating AVPD. A correlation to ejection fraction (EF) has been demonstrated in patients with coronary artery disease(More)
A new color Doppler myocardial imaging (CDMI) system with high spatial and temporal resolution and novel postprocessing modalities has been developed that could allow quantifiable stress echocardiography. The purpose of this study was to determine whether regional myocardial systolic velocities could be accurately and reproducibly measured both at rest and(More)
Diastolic dysfunction is an important cause of cardiac heart failure. To date detailed assessment of diastolic left ventricular (LV) function has required invasive methods which are impractical in the clinical routine. The prevailing non-invasive method has been Doppler echocardiography with use of mitral inflow and pulmonary vein inflow parameters,(More)
BACKGROUND Left ventricular involvement in arrhythmogenic right ventricular cardiomyopathy (ARVC) is a common finding in autopsy studies. In clinical studies using myocardial scintigraphy, MRI and echocardiography, contradictory results have been reported. In this study, we therefore investigated a group of 15 patients with ARVC using thallium-201 (Tl)(More)
The present study sought to investigate the effects of preexercise stretching on delayed onset muscle soreness (DOMS), i.e. soreness, tenderness and loss of muscle force, that usually occurs after strenuous or unaccustomed eccentric exercise. Ten female volunteers performed 10 sets of 10 maximal isokinetic eccentric contractions for knee flexion with both(More)
Controversy exists regarding the validity of various techniques for estimating rates of protein synthesis in vivo. In the present report, we have compared estimates of hepatic protein synthesis in normal mice with a pulse labelling of [1-14C]leucine and calculated hepatic protein synthetic rates in a conventional two-pool model and in a five-pool(More)
Abnormal right heart function after cardiac surgery is a well-known finding. Inadequate preservation during the operation and restricted cardiac motion due to pericardial adhesions have been proposed as underlying mechanisms. This study focuses on the impact of a pericardial substitute implantation on right ventricular function, using echocardiography and(More)
Localized muscle fatigue in the masseter muscle was studied with a method based on power spectrum analysis of myoelectric signals. Under the influence of fatiguing contractions, a gradual shift of the spectral curve occurred; the rate of change was taken as a measure of the development of fatigue. The fatigue was dependent on the bite force. The existence(More)
A solid-phase chemiluminescent immunoassay (LIA) for the determination of cortisol in serum specimens has been developed. The separation of the cortisol onto the solid-phase distinguishes this particular assay from other chemiluminescence immunoassays. The method can be used without prior extraction. Cortisol molecules were made chemiluminescent by(More)
