Electrocardiogram 12-lead

Indicated for patients with ischemic symptoms of <12 h in duration and 12-lead electrocardiogram (ECG) evidence of ... [Pg.27]

Patients with ischemic chest discomfort and suspected acute coronary syndrome are risk-stratified based upon a 12-lead electrocardiogram, past medical history, and results of the creatine kinase myocardial band and troponin tests. The diagnosis... [Pg.83]

Acute coronary syndromes Ischemic chest discomfort at rest, most often accompanied by ST-segment elevation, ST-segment depression, or T-wave inversion on the 12-lead electrocardiogram. Furthermore, it is caused by plaque rupture and partial or complete occlusion of the coronary artery by thrombus. Acute coronary syndromes include myocardial infarction and unstable angina. Former terms used to describe types of acute coronary syndromes include Q-wave myocardial infarction, non-Q-wave myocardial infarction, and unstable angina. [Pg.1559]

Barium sulfate is used to visualize the GI tract.105 Barium sulfate should be avoided in a patient with GI obstruction. It is insoluble and nontoxic but is a soluble compound, which is toxic and may lead to death. Constipation may be detected on oral and rectal administration, and is remedied if a large amount of water is given to the patient. A barium sulfate enema causes electrocardiogram abnormalities. Pneumonitis or granuloma formation are reported during accidental aspiration into lungs. Hypersensitivity reactions also have been reported.106... [Pg.306]
