To provide an artificial heart which sets aside a heart of a patient and leaves the heart of the patient in a body, captures excitation which is generated on a conduction system for taking charge of a heart's beating rhythm under adjustment by a cardiac nerve, which is beaten in synchronization with a beating rhythm of the patient's heart, and which bypasses a part of blood flowing from a vena cava to the heart and feeding the part of the blood to an aorta.SOLUTION: An artificial heart comprises: a right atrium and a cardiac chamber cell； a left atrium and a cardiac chamber cell； shrinkage/extension coils 32-36, 33-37, 34-38, 35-39； sinus and atrioventricular node sensors 40, 41； and sinus and atrioventricular node secondary coils 48, 49.SELECTED DRAWING: Figure 10【課題】患者の心臓を温存して体内に残し、心臓神経による調節の下に心臓の拍動リズムをつかさどる刺激伝導系に起こる興奮を捕え、患者の心臓の拍動リズムに同期して拍動させ、大静脈からその心臓に流れる血液の一部をバイパスさせ大動脈に送り出す人工心臓を提供する。【解決手段】右心房および心室セル、左心房および心室セル、縮みおよび伸び動作コイル３２－３６、３３－３７、３４－３８、３５－３９、洞房および房室結節センサー４０、４１、および洞房および房室結節二次コイル４８、４９などを組み合わせる構造から成る人工心臓。【選択図】図１０
