They are fibres which generate AP(action potential) which trigger heart contractions.
cardiac muscle
Not exclusively:Cardiac Muscle cells are either contractile cells or autorhythmic cells. The majority are contractile.Examples of autorhythmic cells:Sinoatrial (SA), or Sinus, NodeAtrioventricular (AV) NodeAtrioventricular (AV) Bundle (occasionally referred to as the bundle of His)Right and Left Bundle BranchesPurkinje Fibers
Autorhythmic cells in the heart generate electrical impulses that spread through the atria and ventricles via specialized conduction pathways, such as the atrioventricular node, bundle of His, and Purkinje fibers. These pathways allow for coordinated depolarization of the muscle cells, ultimately leading to contraction of the heart chambers.
Cardiac muscle is considered autorhythmic, meaning it has the ability to generate its own electrical impulses without the need for external stimulation. This property allows the heart to beat independently of nerve input.
It would cause the heart to stop beating in a autorhythmic fashion.
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.

Just a guess but the fibers in clothing. ( cotton fibers, polyester fibers, etc)
The fibers which are made by man are the synthetic fibers.
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
