Role of 12 lead ECG Q-waves as a marker of myocardial infarction in the era of cardiac magnetic resonance

Background Q-waves on 12 lead ECG is considered a marker of a large and/or transmural myocardial infarction (MI). Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) accurately identifies myocardial infarction and has become the gold standard for the assessment of myocardial viability. However, CMR is not universally available and clinicians often have to make assumptions ...

Fragmented wide QRS on a 12-lead ECG: a sign of myocardial scar and poor prognosis.

BACKGROUND Fragmented QRS (duration <120 ms) on a 12-lead ECG represents myocardial scar in patients with coronary artery disease. However, the significance of fragmented QRS has not been defined in the presence of a wide QRS (wQRS; duration >or=120 ms). We postulate that fragmented wQRS (f-wQRS) due to bundle branch block, premature ventricular complexes, or paced rhythms (f-pQRS) signify myoc...

Measuring myocardial scar by CMR.

c r o “ e m s d r w n Late gadolinium enhancement (LGE) using cardiac magnetic resonance (CMR) has emerged as the gold-standard technique for imaging of myocardial scar. The basic principle is inversion-recovery imaging after a 5to 10-min delay following intravenous administration of gadolinium contrast (1). With appropriate settings, normal myocardium appears nulled or black, whereas nonviable...
