What is unstable angina, preinfarct angina, and "crescendo angina Correct Answer Synonyms used to describe the new onset of cardiac ischemic chest pain at rest but without evidence of acute myocardial infarction (MI). Reports of symptoms at rest are more likely to be associated with? Correct Answer Coronary artery vasospasm, a condition usually seen in patients with coronary atherosclerosis The pain of costochondritis (a type of chest wall syndrome [CWS]) is often described as? Correct Answer Localized, and it may be replicated with arm movement or pressing on the area of tenderness (point tenderness) How is pain associated with angina pectoris described?

Ambulatory cardiac monitoring (Holter monitoring) until at least one event is recorded is most helpful in ascertaining the presence of a potentially lethal cardiac rhythm disturbance. Echocardiography may be necessary to assess cardiac outflow tract patency and to help rule out valvular stenosis or hypertrophic cardiomyopathy. Syncope is a loss of consciousness that occurs abruptly as a discrete episode and usually lasts for a short period of only a few minutes. What is the pathology of syncope? Correct Answer The implied pathology is decreased cerebral blood flow caused by a
