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)
In order to investigate if genetic factors could be involved in the pathogenesis of hypertrophic obstructive cardiomyopathy, we determined HLA-A, HLA-B, HLA-C, and HLA-DR specificities in 12 Italian patients affected with the disease and in healthy family members of one of them. HLA-DR3 was found in 50% of patients as compared to 17.1% of normal control(More)
Cardiovascular tests (CT) of autonomic function and non-invasive ambulatory blood pressure (BP) and heart rate (HR) monitoring were performed in 17 patients with multiple system atrophy (MSA) (mean age 61 +/- 9 years) and in 12 healthy subjects matched for sex and age. CT showed severe autonomic dysfunction with orthostatic hypertension (OH) in eight(More)
We analysed the performance of the electrocardiogram in diagnosing left ventricular hypertrophy in 70 patients with isolated left anterior hemiblock and in 75 patients with right bundle branch block, either isolated (44 cases) or associated (31 cases) with left anterior hemiblock. Left ventricular hypertrophy defined as an echocardiographically determined(More)
Myotonic dystrophy is an autosomal dominant disease affecting many organ systems, including the heart. Abnormalities of the cardiac conduction system are a frequent and well-documented finding in this neuromuscular disease, whereas overt signs of heart failure are rarely reported. However, controversy exists about the prevalence of preclinical left(More)
To determine the independent effects of left bundle branch block (LBBB) on global and regional left ventricular (LV) function we performed equilibrium radionuclide angiocardiography at rest in 3 patients with chronic LBBB (group I, mean age 53.6 years and in 6 patients with intermittent LBBB (group II, mean age 41.5 years). All patients were judged to have(More)
This study was undertaken to evaluate autonomic nervous system function in patients with gastroesophageal reflux disease. Based on clinical criteria, 28 consecutive patients with no history of heart, metabolic, or neurologic disease (mean age 41 y, range 20–62 y) reporting with upper gastrointestinal symptoms typical of gastroesophageal reflux underwent(More)
