To determine the natural history of left ventricular function at rest and during exercise and to assess the impact of this variable on subsequent mortality, 165 patients were studied with radionuclide angiography within 24 hours of acute myocardial infarction. The ejection fraction of the 19 patients who died during the 6 month follow-up was lower than that(More)
Although biofeedback has been used as a first-line therapy for fecal incontinence, it is known to be time consuming and demands attendance to a hospital during the whole period of treatment. In this study, we describe a new biofeedback device specifically developed for home treatment of fecal incontinence, which consists of a microprocessor controlled unit(More)

METHODS We designed a cross sectional study conducted in individuals aged 18 years and older. Perception of dyspnea was assessed using an inspiratory resistive load system. Dyspnea was assessed during(More)
Background: Breath-holding test has been tested in some clinical scenarios and has proved to be of clinical utility. Objectives: To determine the maximum voluntary breath-holding time in patients with obstructive ventilator defects and in normal subjects and to correlate the breath-holding times with pulmonary function tests. Methods: We conducted a(More)
