چکیده
We report a case of cardiac asystole during dobutamine stress echocardiography in a 59 year-old woman presenting with chest pain and a positive treadmill test for ischemia. Cardiac asystole was not associated with myocardial ischaemia and was probably related to a powerful cardioinhibitory reflex caused by dobutamine stimulation.

Syncope caused by cardiac asystole during dobutamine stress echocardiography.
Syncope caused by cardiac asystole during dobutamine stress echocardiography occurred in a 60 year old woman presenting with chest pain and a non-diagnostic exercise test. Cardiac asystole was not associated with myocardial ischemia and was attributed to a powerful cardioinhibitory vagal reflex elicited by the stimulation by the drug of cardiac and aortic mechanoreceptors. Cardiac asystole was ...
متن کاملCoronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report
Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...
متن کاملThe long prognostic value of wall motion abnormalities during the recovery phase of dobutamine stress echocardiography after receiving acute beta-blockade.
OBJECTIVE To assess the prognostic value of wall motion abnormalities during the recovery phase of dobutamine stress echocardiography in addition to wall motion abnormalities at peak stress. METHODS Wall motion abnormalities were assessed at peak and during recovery phase of dobutamine stress echocardiography in 187 consecutive patients, who were followed for occurrence of cardiac events. R...

OBJECTIVES To compare non-invasive determination of cardiac index (CI) by whole body electrical bioimpedance using the NICaS apparatus and Doppler echocardiography, and the role of cardiac power index (Cpi) and total peripheral resistance index (TPRi) calculation during dobutamine stress echocardiography (DSE). SUBJECTS AND METHODS We enrolled 60 consecutive patients undergoing DSE. Patients ...
متن کاملRole of dobutamine stress echocardiography in predicting outcome in 860 patients with known or suspected coronary artery disease.
BACKGROUND Increasingly, dobutamine stress echocardiography has been used for detection of coronary artery disease. Less information exists regarding the incremental prognostic value of the test, including semiquantitative wall scoring, compared with clinical and rest echocardiographic variables. METHODS AND RESULTS Follow-up information was obtained from 860 patients who underwent dobutamine...
