DSE (Dobutamine Stress Echo)
DSE (Dobutamine Stress Echo)
DSE (Dobutamine Stress Echocardiography) is a specialized cardiac ultrasound examination used to evaluate heart function when a patient is unable to perform physical exercise. During the procedure, Dobutamine, a cardiac stimulant medication, is administered intravenously to increase the heart rate and mimic the effects of exercise while echocardiographic images are obtained to assess cardiac performance and detect coronary artery disease.
