Uso temprano de atropina en la ecocardiografía de estrés con dobutamina

Early use of atropine in dobutamine stress echocardiogram.Introduction: stress echocardiograms may be limited if target heart rate is not achieved, and infusion time can be prolonged. Objectives: to assess the early use of atropine, and its relation with the number of studies that do not achieve 85% target of heart rate; the study duration, and the frequency of adverse events. Methodology: stress echocardiograms were retrospective reviewed. According to atropine use the patients were grouped: group I: no atropine, group II: late use (>20 μg/Kg/min), and group III: early use (≤20 μg /Kg/min). Results: 389 patients were included, with a mean age of 63.9 (18-89 years), distributed: group I: 85, group II: 46, and group III: 258. The mean study duration was significantly lower for group III: 15.01 min (SD: 2.97), compared with groups I: 18.67 min (SD 3.66) and II: 22.43 min (SD 5.40). The presence of symptoms during the infusion was lower for group III: 2.71%, compared with groups I: 18% and II: 12%. The stress echocardiogram was negative in 90.2% patients, positive in 3.9, and non-diagnostic in 5.9%. The percentage of non-diagnostic tests was greater in group I, and the least percentage was found in group III. Conclusions: early use of atropine facilitates that a greater number of patients achieve target heart rate, in less study time and a lower incidence of adverse events. We recommend stimulating the early use of atropine in stress echocardiography. (MÉD.UIS. 2011;24(3):247-52).Key words: Dobutamine. Atropine. Adverse events.
