Rest exam: A 66year old lady with progressively increasing breathlessness. Resting study normal. Unable to perform exercise, then patient was referred for pharmacological stress echocardiography. Normal perfusion at rest in all territories (as expected given normal wall motion) Stress exam: Repeat imaging performed after dobutamine intravenous infusion. Heart rate 130-140bpm, so full replenishment expected in 3-4beats (see Chapter on practice). Note the rapid replenishment indicating normal perfusion in all walls.
