You are reviewing an ECG you arranged for a 56-year-old man with newly diagnosed hypertension. The trace is normal but the computerised report notes ‘first-degree heart block’. Looking at the ...

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 ...

An EKG measures the heart’s electrical activity and can detect various issues, including heart attacks, rhythm abnormalities, and electrolyte imbalances. Seek immediate medical help if you experience ...

NEW YORK (Reuters Health) - The results of a new study suggest that patients with psoriatic arthritis, a form of rheumatoid arthritis accompanied by psoriasis, may have "subtle" cardiac conduction ...

In second-degree type II AV nodal block (a.k.a. Mobitz Type II AV block), the AV node becomes completely refractory to conduction on an intermittent basis. For example, three consecutive P waves may ...

Atrioventricular reentrant tachycardia occurs when a reentrant circuit is present outside of the AV node through an abnormal conduction pathway that connects the atrium to the ventricles. If an action ...

More than 300 million EKGs (short for electrocardiogram, a test that checks heart rhythm and electrical signals of the heart) are conducted around the world each year, according to a study published ...

Several ECG markers of atrial or AV nodal mechanical/substrate/electrical conduction abnormalities have been related to both incident AF and stroke. P terminal force ...
