Background Previous epidemiological studies demonstrated that premature atrial contractions (PACs) and premature ventricular ...

A left ventricular aneurysm can be diagnosed on ECG when there is persistent ST segment elevation occurring 6 weeks after a known transmural myocardial infarction (usually an anterior MI). Without ...

Background and objective Prior studies have suggested that patients with premature ventricular complexes (PVCs) may have an increased risk for atrial fibrillation (AF) and stroke. It is unclear ...

Dear Doctor: About 15 years ago, while giving blood, I was advised of an irregularity, which my doctor confirmed after an EKG, known as premature ventricular contractions. He told me not to worry, and ...

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 ...

An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart disease. It's done through small ...

Sometimes, an abnormal EKG reading is a normal variation in a person’s heart rhythm. In other cases, it may be due to an underlying heart condition or a reaction to medication. An electrocardiogram ...

Communicating concerns about nonspecific changes on ECG Exercise caution when a patient presents with acute chest pain. The ability to explain the situation as clearly as possible is essential.

Depending on how the heart’s electrical activity appears on an EKG, a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the ...
