Background: Some patients with acute myocardial infarction presenting without significant
ST segment elevation develop a Q-wave infarction. It is unclear whether these patients can …

Serial 12-lead electrocardiogram and plasma creatine kinase (CK)-MB values from 544
patients with confirmed non-Q-wave acute myocardial infarction (AMI) were analyzed to …

Aims The prognostic significance of pathological Q waves appearing in the acute phase of
myocardial infarction has not been determined. We investigated whether new Q waves on …

Q waves can develop early in infarction and indicate infarct progression better than symptom
duration. ST resolution (STR) is a predictor of reperfusion success. Our aim was to assess …

Objectives To evaluate quantitative relationships between baseline Q-wave width and 90-
day outcomes in ST-segment elevation myocardial infarction (STEMI). Background Baseline …

Background Q wave is typically a late finding on ECG during STEMI and consequently,
when Q wave is found on the first ECG, many patients do not receive reperfusion therapy. In …

In spite of the apparent rising prevalence of non-Q wave myocardial infarction (MI), and the
widespread applicability of cardiac enzymes in the diagnosis of myocardial necrosis, all …

Acute ST segment elevation is regarded generally as the sine qua non of evolving Q wave
myocardial infarction (MI) because such electrocardiographic (ECG) injury is believed to be …

Background: Q waves developed in the subacute and persisting into the chronic phase of
myocardial infarction (MI) usually signify myocardial necrosis. However, the mechanism and …

The classification of Q-wave versus NQWMI was based on the presence or absence of Q
waves 24 h after hospital admission. It has been documented that at least 10% of patients …
