The diagnosis is sinus rhythm with interpolated premature ventricular complexes, in a trigeminal pattern, with retrograde concealed conduction. The rhythm is irregular, but there is a repeating ...

Abstract 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 ...

Several points of convincing evidence in the upper strip indicate that the rhythm is VT. First, the beginning of the wide QRS tachycardia near the end of the strip is not preceded by a P wave, proving ...

Background A routine sports evaluation identified constant alternation between a junctional and idioventricular rhythm in a 9-year-old child. During exercise testing, electrography demonstrated that ...

Dr Michele Orini shares how machine learning can help identify critical VT ablation targets for a safer, data-driven ...
