What is dobutamine stress echocardiography?

Echocardiography is ultrasound imaging of the heart. Usual stress test for the heart is exercise ECG in which serial ECG recordings are done during a graded exercise protocol, usually on a treadmill. ECG is the recording of the electrical activity of the heart. There are certain conditions like left bundle branch block in which an exercise ECG becomes uninterpretable. Left bundle branch block is the lack of signal conduction in left bundle branch taking signals to the lower left chamber of the heart. In that case, a medication known as dobutamine is given as drip into the blood vessels and serial echocardiograms done to assess the response of heart to stress. This is known as dobutamine stress echocardiography. It is also useful in those who cannot exercise due to medical problems or physical disability.
