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 ...

See related research article by Siha and colleagues on page 1135 and at www.cmaj.ca/lookup/doi/10.1503/cmaj.111683 One could imagine a scenario in which attention to ...

If it’s important that an ECG is done, it’s important that it’s legible. Asking patients to hold their breath for a couple of seconds can help, or if fine tremor is a problem, try moving the limb ...

The diagnosis is NSR, isorhythmic dissociation, acute ST-segment elevation MI (STEMI) of the lateral wall, and poor R-wave progression across the precordium (clockwise rotation). The rhythm is regular ...

In this review, the authors discuss the role of ECG in prediction of stroke. ECG plays an important role in detection of several stroke risk factors/predictors including atrial fibrillation and left ...

A rather anxious 23-year-old man attends with palpitations. A careful history suggests simple ectopic beats, perhaps exacerbated by his anxiety. There are no red flags in the history, he is a ...

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 ...
