A myocardial infarction can be thought of as an elecrical 'hole' as scar tissue is electrically dead and therefore results in pathologic Q waves. Pathologic Q waves are not an early sign of myocardial infarction, but generally take several hours to days to develop. Once pathologic Q waves have developed they rarely go away.Unstable angina (UA), nonQ wave myocardial infarction (NQMI), and Q wave myocardial infarction (QMI) constitute the diagnoses collectively termed the acute coronary syndromes. All are related pathogenetically, as each represents different stages of plaque rupture and thrombosis. non q wave mi wikipedia

The total size of MI was a better predictor of Qwave vs nonQwave classification than the transmural extent; the latter did not significantly increase the area under the ROC curve with multivariant analysis, and was not an independent predictor of Q vs nonQ MI.

NonQwave myocardial infarction is a heterogeneous group of disorders and includes true posterior transmural ( Qwave ) infarctions without manifest Q waves on the scalar 12lead electrocardiogram, subendocardial infarctions with transient STwave and Twave changes, intramural infarctions with giant negative T waves Unstable angina (UA) is a type of angina pectoris that is irregular. It is also classified as a type of acute coronary syndrome (ACS). It can be difficult to distinguish unstable angina from nonST elevation (nonQ wave) myocardial infarction (NSTEMI).non q wave mi wikipedia A nonQ wave myocardial infarction refers to a myocardial infarction that does not result in a Q wave on the 12lead ECG once the infarction is completed. The terms Q wave MI, nonQ wave MI

Apr 21, 2009 However, not all patients with MI develop Qwaves. In patients who initially present acutely with nonQwave MI, only about 15 will develop Qwaves. Therefore it is likely that a substantial number of patients with UMI will be missed if the criteria for identifying MI is only Qwaves and nil else on ECG. non q wave mi wikipedia Jan 07, 2012 NonST elevation MI (new term for nonQ wave MI, often referred to as nonSTEMI), is an unstable coronary syndrome which is differentiated from unstable angina by a subsequent rise in cardiac enzymes. ECG findings often include ST depression but do not include new pathological Q waves. NonST elevation MI (new term for nonQ wave MI, often referred to as nonSTEMI), is an unstable coronary syndrome which is differentiated from unstable angina by a subsequent rise in cardiac enzymes. ECG findings often include ST depression but do not include new pathological Q waves. nonQ wave infarction myocardial infarction not characterized by abnormal Q waves. pulmonary infarction localized necrosis of lung tissue, due to obstruction of the arterial blood supply. Q wave infarction myocardial infarction characterized by Q waves Myocardial infarction (MI) refers to tissue death of the heart muscle (). It is a type of acute coronary syndrome, which describes a sudden or shortterm change in symptoms related to blood flow to the heart. Unlike other causes of acute coronary syndromes, such as unstable angina, a myocardial infarction occurs when there is cell death, as measured by a blood test for biomarkers (the cardiac
