Electrical signals cause the heart to beat and can cause severe cardiac events like tachycardia and fibrillation as they spiral outward in spiral waves
Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation
Harvard University researchers, in collaboration with colleagues from Emory University, have developed the first fully autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by recreating the muscle contractions of a pumping heart, bringing researchers one step closer to developing a more complex artificial muscular pump and providing a platform to study heart disease like arrhythmia.
