The ECG findings of an old myocardial infarction are Q waves, specifically for an inferior MI, Q wave in leads II, III, and aVF. Remember a pathologic Q wave indicating an old MI is defined as Q ...

With the knowledge derived from a 12-lead ECG, ... Significant myocardial salvage can be accomplished in patients with new pathological Q waves and, even after 2 hours, ...

8. If the digital analysis states ‘anteroseptol infarct, probably old’, ask if there really are and pathological Q waves. First thing to check is whether or not there is any positive upward deflection ...

This ECG shows normal sinus rhythm. There are small narrow Q waves in II-III-AVF that do not fulfill the criteria for “pathologic” Q waves (> 0.2 second or > 5 mV). The QTc (Fridericia’s ...

Background In athletes, ECG changes from physiological cardiac remodelling are common but can overlap with findings from a pathological disorder. We compared ECG findings in a group of elite high ...
