ABSTRACT
Objective To study the clinical value of portable echocardiography system in diagnosis for acute paroxysmal dyspnea.Methods Clinical data of 81 patients with acute paroxysmal dyspnea recorded by a portable echocardiography apparatus at their bedside were retrospectively analyzed,and compared to those of 45 patients by conventional echocardiography.Results The 2D images in portable echocardiograph were similar to those of conventional echocardiograph.Diagnosis could be established in 74 (91.4%),corrected in six (7.4%) and not confirmed only in one (1.2%) of 81 patients with acute paroxysmal dyspnea by portable echocardiography system.And,portable echocardiography system could be used to diagnose pericardial effusion and to monitor perieardial puncturing and draining at bedside. Conclusions Portable echocardiography systems can provide rapid,accurate and valuable information on diagnosis and treatment for acute paroxysmal dyspnea,and make its clinical intervention accurate,scientific and effective,bringing echocardiography performed at bedside possible.
