Abstract(in English) | The critical mass hypothesis says critical amount of myocardium is needed to maintain the ventricular fibrillation. We evaluated this hypothesis by using 3-D tissue models with the Luo-Rudy model. We constructed a parallelepipedal slab and a human ventricular shaped model. The critical mass in each model was 480, 000 units and 420, 000-550, 000 units, respectively, which corresponded to 7.2-9.4cm^3 of the myocardium. When the tissue volume was the same, the fibrillation became difficult to maintain as the surface area of the tissue widened. The fibrillation terminated when the surface to volume ratio (S/V) was over 3.5. We concluded that the maintenance of the fibrillation is determined by the S/V of the tissue rather than only the critical mass. |
