Electrocardiographic predictors of atrial fibrillation.

29 Sep 2009 BACKGROUND: Atrial fibrillation (AF) is the most prevalent arrhythmia in the United States and accounts for more than 750,000 strokes per year. Noninvasive predictors of AF may help identify patients at risk of developing AF. Our objective was to ... Read more...

Potential roles of cell-derived microparticles in ischemic brain disease.

29 Sep 2009 PURPOSE: The objective of this study is to review the role of cell-derived microparticles in ischemic cerebrovascular diseases. MATERIALS AND METHODS: An extensive PubMed search of literature pertaining to this study was performed in April 2009 ... Read more...

Ultrastructural and functional remodeling of the coupling between Ca2+ influx and sarcoplasmic reticulum Ca2+ release in right atrial myocytes from experimental persistent atrial fibrillation.

15 Sep 2009 RATIONALE: Persistent atrial fibrillation (AF) has been associated with structural and electric remodeling and reduced contractile function. Objective: To unravel mechanisms underlying reduced sarcoplasmic reticulum (SR) Ca(2+) release in persistent ... Read more...

Technical information about 'Atrial Fibrillation'

Definition: Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
