[Why does our heart fibrillate?- or what goats can teach us]

Our present knowledge about cardiac electrophysiology is based on numerous experiments and discoveries going back to the Greek antique and ancient Egypt. Exploration of cardiac anatomy was followed by the description of circulation and cardiac physiology in the 17th century. In the early 20th century cardiac electrophysiology became the new field of interest and was studied with the help of numerous animal experiments (squid, rays, dogs, goats, mice and other species). We ought to be grateful for the knowledge and possibilities in modern medicine that were made possible by the great number of researchers, patients and animals that contributed to this.
