Certificate of Analysis. Human Cardiac Fibroblasts (HCF) Primary Human Cardiac Fibroblasts (HCF) are isolated from the ventricles of an adult heart. They play a central role in the maintenance of the extracellular matrix in the normal heart and the synthesis of growth factors and cytokines.
In atrial fibrillation (AFib), the heartâs two small upper chambers (atria) donât beat the way they should. Instead of beating in a normal pattern, the atria beat irregularly and too fast, quivering like a bowl of gelatin. Itâs important for the heart to pump properly so your body gets the oxygen and food it needs. What Is Atrial Fibrillation? Cardiovascular Conditions Your heart has a natural pacemaker, called the âsinus node,â that makes electrical signals. These signals cause the heart to contract and pump blood. With atrial fibrillation, random electrical activity interrupts the normal conduction rhythm. This prevents the atria from properly contracting.
