We performed signal-averaged electrocardiography and 24-h ambulatory electrocardiographic monitoring in 53 patients with myotonic dystrophy to determine the incidence and clinical significance of ventricular late potentials. Patients were followed up for a mean period of 31 +/- 17 months (range 11-68 months). At entry, none of the patients had bundle branch(More)
INTRODUCTION Calcification of the ductus and ligamentum Botalli with no cardio-respiratory symptoms is normally a sign of their closure. However, as the calcification can be associated with a patent duct or a ductal aneurysm, its presence must not be misinterpreted. The frequency and the different patterns of this calcification must be known, as well as is(More)
We utilized Doppler echocardiography to characterize left ventricular diastolic function in 42 patients with myotonic dystrophy (mean age 37 +/- 12 years, 64% male) who had no symptoms of heart failure and had normal left ventricular systolic function. Data were compared with those in 41 normal control subjects of similar age and gender. Heart rate,(More)
To evaluate the influence of autonomic function on the QT interval and QT dispersion, 18 patients (10 males and 8 females; mean age 61±9 years) with multiple system atrophy (MSA, Shy-Drager syndrome) were studied. Cardiovascular tests were performed to assess the degree of autonomic dysfunction. The QT interval, corrected QT (QTc), QT dispersion (QTd),(More)

A roundtable panel of national and regional managed care decision makers and providers met to discuss pulmonary arterial hypertension (PAH) and strategies for management. As a rare, complex disease with high economic costs and potentially devastating outcomes, PAH necessitates that managed care providers balance optimal care with efficient use of healthcare(More)
We analysed the diagnostic performance of the signal-averaged QRS duration for the detection of left ventricular hypertrophy in 100 consecutive outpatients (62 men and 38 women; mean age, 49.8 +/- 11.8 years) with essential hypertension and compared the results with some of the currently employed electrocardiographic criteria. Forty-eight healthy subjects(More)
We analyzed the performance of the electrocardiogram in the diagnosis of left atrial enlargement in 1000 unselected consecutive patients (585 men and 415 women, mean age 46 +/- 17 years) with different cardiovascular diseases or clinically normal. Echocardiography was used as reference method to assess left atrial dimension. The following(More)
Patients with left bundle-branch block (LBBB) often present electrocardiographic abnormalities and, therefore, are excluded from studies concerning electrocardiographic evaluation of ventricular repolarization. The aim of the study was to assess whether LBBB could influence dispersion of ventricular repolarization. Surface electrocardiograms of 16 patients(More)
