WebDobutamine has a variable effect on heart rate, but it can significantly increase heart rate (particularly at the higher concentrations used in stress echocardiography). 8,54 After cardiopulmonary bypass the primary mechanism of increased cardiac output by dobutamine is an increase in heart rate (approximately 1.4 beats/min per microgram per … WebDobutamine stress echocardiography (DSE), like exercise echocardiography, has found its primary application in ischemic heart disease, with roles in identification of obstructive epicardial coronary artery disease, detection of viable myocardium, and assessment of the efficacy of anti-ischemic medical therapy in patients with known coronary artery disease.
WebNov 28, 2014 · Dobutamine augments myocardial contractility via strong B1R stimulation with mild to moderate B2R agonism and mild A1R agonism, producing a strong dose-dependent increase in SV and CO with moderate increases in HR and a variable effect on MAP (Tables 1 and 2). 2 Dobutamine modestly lowers the SVR, except at high doses … WebOct 19, 2008 · The increased inotropic effects are greater than those seen with dobutamine and the decrease in SVR is greater than seen with nitroprusside. Milrinone is a better drug choice, in my opinion, for the patient with severe heart failure than dobutamine. This turned out to be a very in depth response to a simple question, and I apologize for that.
