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%, according to new research ...

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 left atrium, which was not markedly dilated or greatly thickened, was almost completely filled by a firm, organized thrombus attached to the posterior, lateral and anterior sides of the atrium, ...

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 ...

The normal mitral valve permits unrestricted antegrade diastolic flow from the left atrium to the left ventricle (LV) and effectively seals off the atrium from the ventricle during LV systole, ...

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 ...

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 ...
