Background The presence of pathologic Q waves on admission electrocardiogram (ECG) in
patients with anterior ST‐elevated myocardial infarction (STEMI) has been related to …

Objectives: We assessed the incremental value of baseline Q waves over time from
symptom onset as a marker of clinical outcome in ST-segment elevation myocardial …

Abstract Background Pathological Q waves (QWs) in the first ECG recorded at hospital
admission has been found to correlate with myocardial damage and mortality in STEMI …

Background Presence of Q waves on the presenting electrocardiogram (ECG) in patients
with ST‐segment elevation myocardial infarction (STEMI) has been associated with worse …

For patients presenting> 12 hours after symptom onset, the 2013 American College of
Cardiology/American Heart Association guidelines provide a Class IIa; Level of Evidence B …

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

BACKGROUND: The presence of Q waves at presentation with a first acute ST-segment
elevation myocardial infarction (STEMI) reflects a more advanced stage of the infarction …

Background Pathological Q waves are correlated with infarct size, and Q-wave regression is
associated with left ventricular ejection fraction improvement. There are limited data …

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 …

Background: In ST-segment elevation myocardial infarction (STEMI), QRS score at
presentation ECG may reflect the progression of infarction and facilitate prediction of the …
