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 …

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 …

Aims To compare the outcome of short-and long-term survival of patients with Q wave vs non-
Q wave myocardial infarction. Methods A total of 6676 patients with acute myocardial …

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 …

In a totally nonselected group of patients with acute myocardial infarction (AMI)(n= 921)
admitted from the emergency department to the coronary care unit or other hospital ward …

OBJECTIVES.: The purpose of this study was to determine the time course of the
appearance of abnormal Q waves on the electrocardiogram (ECG) over the first 6 h of …

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 …

Acute myocardial infarction may be associated with the development of Q waves on the
electrocardiogram (ECG), or with changes limited to the ST segment or T wave. The ECG …

The timing of Q-wave evolution and its prognostic significance was studied in 201 patients
who received thrombolytic therapy for a first acute myocardial infarction (AMI). One hundred …

The long-term prognostic implications of the electrocardiographic location of a myocardial
infarction and the subsequent retention or disappearance of diagnostic Q waves were …
