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 formula) is ...

Hypertrophic obstructive cardiomyopathy (HOCM) is a pathologic cardiac condition in which the interventricular septum is abnormally thickened. The classic finding in HOCM is large dagger-like “septal ...

Background: Baseline Q waves may provide additional value compared with time from the onset of symptoms in predicting outcomes for patients with ST-segment elevation. We evaluated whether baseline Q ...

Background Interpretation of the athlete’s ECG is based on differentiation between benign ECG changes and potentially pathological abnormalities. The aim of the study was to compare the 2010 European ...

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 ...
