Mitochondria and arrhythmias

Free Radical Biology and Medicine, 2014
Mitochondria are essential to providing ATP, thereby satisfying the energy demand of the incessant electrical activity and contractile action of cardiac muscle. Emerging evidence indicates that mitochondrial dysfunction can adversely affect cardiac electrical functioning by impairing the intracellular ion homeostasis and membrane excitability through ...

C-Reactive Protein Elevation in Patients With Atrial Arrhythmias: Inflammatory Mechanisms and Persistence of Atrial Fibrillation

Circulation, 2001
Background—Atrial fibrillation (AF) may persist due to structural changes in the atria that are promoted by inflammation. C-reactive protein (CRP), a marker of systemic inflammation, predicts cardiovascular events and stroke, a common sequela of AF.
