Myocardial ischemia electrocardiogram

Electrocardiogram (ECG) May be normal or could show numerous abnormalities including acute ST-T-wave changes from myocardial ischemia, atrial fibrillation, bradycardia, and LV hypertrophy. [Pg.39]

Acute coronary syndromes is a term that includes all clinical syndromes compatible with acute myocardial ischemia resulting from an imbalance between myocardial oxygen demand and supply.3 In contrast to stable angina, an ACS results primarily from diminished myocardial blood flow secondary to an occlusive or partially occlusive coronary artery thrombus. Acute coronary syndromes are classified according to electrocardiogram (ECG) changes into STE ACS (STE MI) or NSTE ACS (NSTE MI and unstable angina) (Fig. 5-1). An STE MI, formerly... [Pg.84]

Cardiovascular Effects. Transient electrocardiogram alterations, indicative of myocardial ischemia, were observed in an individual burned by an unknown amount of white phosphorus (Summerlin et al. 1967). The electrocardiogram returned to normal 5 days after being burned. [Pg.91]

This grouping of clinical syndromes are compatible with myocardial ischemia, and a prompt visit to the emergency department is indicated. Electrocardiograms in the emergency department would differentiate a NSTEMI from a STEMI, the latter suggesting a greater degree of myocardial ischemia. [Pg.465]

No cardiovascular effects are seen at the recommended daily dose. At a dose of 0.1 mg of salmeterol twice a day no change in heart rate or rhjdhm was seen on a 24-hour electrocardiogram (Holier). No change in blood pressure was seen and no electrocardiographic abnormality related to myocardial ischemia was recorded during 24-hour monitoring (12). [Pg.3101]

Cardiomyopathy is the most common chemotherapy-associated cardiac toxicity. Myocardial ischemia, pericarditis, arrhythmias, miscellaneous electrocardiogram (ECG) changes, and angina occur much less frequently. The anthracyclines (da-unorubicin, doxorubicin, epirubicin, and idarubicin) have the highest consistent risk for cardiomyopathy, which is cumulative dose related. There is evidence that high-dose cyclophosphamide, mitoxantrone, and fluorouracil also pose an increased risk of cardiac damage. The concurrent use of traztuzu-mab with an anthracycline and cyclophosphamide is associated with a risk of cardiac dysfunction, but the consequences of sequential use are not yet known. [Pg.394]

Cardiovascular Cardiomegaly, myocardial ischemia, murmurs, and abnormal electrocardiogram patients with SCD have lower blood pressure (BP) than the normal population normal BP values for SCD should be used for diagnosis of hypertension ("relative" hypertension) heart failure usually is related to fluid overload... [Pg.1860]

Aortic arch dissection can cause profound hypotension, with global, and sometimes boundary zone, cerebral ischemia or focal cerebral ischemia if the dissection spreads up one of the neck arteries. Clues to this diagnosis are anterior chest or interscapular pain, along with diminished, unequal or absent arterial pulses in the arms or neck and a normal electrocardiogram, unlike acute myocardial infarction, acute aortic regurgitation and pericardial effusion. [Pg.69]

Myocardial Infarction (Ml) has a central area of necrosis surrounded by a zone of Injury that may recover If revascularization occurs. This zone of injury is surrounded by an outer zone of reversible ischemia. Each zone produces characteristic electrocardiogram changes. [Pg.237]

Ischemia, injury, and infarction-the three I s of myocardial infarction (Ml)-produce characteristic electrocardiogram (ECG) changes. The changes shown by leads that reflect electrical activity in damaged areas are shown to tite right of the illustration below. [Pg.246]
