The diagnosis is normal sinus rhythm, interpolated premature ventricular complexes (PVCs) in a trigeminal pattern, retrograde concealed conduction, intraventricular conduction delay, and old inferior ...

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 ...

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 ...

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 ...

QRS interval widening appears to be highly specific for the diagnosis of hyperkalemia in patients with end-stage kidney disease. ECG changes, in general, have poor sensitivities for hyperkalemia in ...

A 62 year old male with a history of hypertension presents to his primary care physician for a routine check-up. His blood pressure is 220/110. He admits to not taking his blood pressure medications ...

This wide QRS complex tachycardia has a typical left bundle branch block pattern, but two things give the clue that this is ventricular tachycardia. There is a fusion beat (second from left) present ...

Investigators from Ghana evaluated cardiac abnormalities among persons living with HIV who were or were not on highly active antiretroviral treatment. Previous results have been mixed on the utility ...
