The atropine factor in pharmacologic stress echocardiography

Early atropine is safer than conventional atropine administration in the elderly undergoing dobutamine stress echocardiography.

BACKGROUND Early injection of atropine during dobutamine stress echocardiography has been demonstrated in retrospective analyses to reduce the duration and dose of dobutamine infusion, while preserving a similar diagnostic accuracy with a lower incidence of adverse effects. AIM In our prospective study, we sought to explore the safety of the early atropine-dobutamine stress echocardiography p...

Pacing stress echocardiography: an alternative to pharmacologic stress testing.

OBJECTIVES We sought to evaluate the diagnostic accuracy and feasibility of bedside pacing stress echocardiography (PASE) as a potential substitute for pharmacologic stress echocardiography in patients admitted to the hospital with new-onset chest pain or worsening angina pectoris. BACKGROUND Accurate and rapid noninvasive identification and evaluation of the extent of coronary artery disease...

Transient global amnesia complicating dobutamine–atropine stress echocardiography

Comparison of exercise, dobutamine-atropine and dipyridamole-atropine stress echocardiography in detecting coronary artery disease

BACKGROUND Dipyridamole and dobutamine stress echocardiography testing are most widely utilized, but their sensitivity remained suboptimal in comparison to routine exercise stress echocardiography. The aim of our study is to compare, head-to-head, exercise, dobutamine and dipyridamole stress echocardiography tests, performed with state-of-the-art protocols in a large scale prospective group of ...

Coronary spasm induced by dobutamine-atropine stress echocardiography.

This is the report on a 45-year-old female, with a history of systemic arterial hypertension and cigarette smoking, submitted to dobutamine-atropine stress echocardiography for the investigation of coronary artery disease. At stress peak, the patient reported sudden, highly intense precordial pain. The 12-lead electrocardiogram showed ST segment elevation in DII, DIII, aVF, V5 and V6, and depre...
