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 ...

The correct diagnosis is sinus tachycardia, left atrial abnormality, and QRS (electrical) alternans, right axis caused by left posterior fascicular block (Figure 2). The rhythm is regular at a rate of ...

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 ...

Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...

This is the last in a three-part series on using an electrocardiogram to assess the heart’s electrical activity. In this article, the focus is on cardiac rhythm and conduction abnormalities of the ...

The QRS complex is positive in lead I and negative in lead II and also negative in lead aVF – indicating left axis deviation TIP When you see RBBB always look for 1 st degree heart block and/or left ...

This page lists all known medications that could potentially lead to 'QRS axis abnormal' as a side effect. It's important to note that mild side effects are quite common with medications. The ...
