A left atrial appendage closure is a procedure your doctor may recommend if: you have atrial fibrillation (also known as AF or AFib) or you are not a good candidate for taking blood thinner medication ...

Atrial fibrillation is caused by an abnormality in the heart’s electrical conduction system. It’s common — around 9 percent of people 65 and over have it. To understand A fib, as it’s often called, it ...

Researchers report that structural or functional abnormalities within the heart’s left atrium, with or without symptoms, may increase a person’s risk of developing dementia later in life by 35%. The ...

The correct diagnosis is normal sinus rhythm, right bundle branch block (RBBB), left anterior fascicular block, bifascicular disease, blocked (nonconducted) premature atrial complexes in a trigeminal ...

The ECG shows regular P waves with terminal P-inversion in V1 (left atrial abnormality). There is no evidence of conduction (complete heart block). The QRS complexes are regular at a rate slightly ...

A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave duration ...

A new study published in the Journal of the American Heart Association has shown that a heart abnormality called atrial cardiomyopathy may increase the risk of developing dementia by 35%. The study ...

The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...
