May support safety of dobutamine stress echocardiography regarding 24-hour arrhythmias; hypothesis-generating and should not yet change practice.
Does dobutamine stress echocardiography increase the risk of arrhythmias or ST-segment deviation during the following 24 hours in patients with coronary artery disease or cardiomyopathy?
Dobutamine stress echocardiography is safe and does not significantly increase the frequency or severity of cardiac arrhythmias in the subsequent 24 hours.
