提出两种两阶段的螺旋波控制方法，第一阶段用正相脉冲力作用快变量，第二阶段用反相脉冲力作用快变量或用正相脉冲力作用慢变量，用修改后的B?r模型进行数值模拟，结果表明：两阶段的脉冲控制方法比单阶段控制方法更有效地控制螺旋波，作用力可以减少到后者力大小的38％～55％。结果建议，可以通过两阶段控制螺旋波的方法改进心脏电除颤。

Modified B?r model is used to study suppression of spiral wave. Methods of suppressing spiral wave by two-stage pulse force control are proposed. In the first stage, fast variable of the model is acted by a positive rectangular pulse force. In the second stage, direction of force is changed to the opposite or the force is acted on the slow variable. It shows that two-stage pulse control method is more efficient than one-stage method, and magnitude of the force is 38% ~55% of the latter. It suggests that two-stage method of control of spiral wave can improve defibrillation efficiency.
