Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

In consideration of the in-pulse phase modulation and Doppler frequency rate-of-change's subtleness, a fast and accurate algorithm is proposed. The influence to parameter estimation with phase modulation is dismissed by time domain correlation between neighboring pulses. Signal noise ratio is increased by frequency domain accumulation.

该文针对信号脉内相位调制和多普勒频率变化率信息非常微弱的特点，提出了一种快速高精度估计算法，通过相邻脉冲间的时域相关消除了相位调制对参数估计的影响，频域积累增强了信噪比，利用脉冲间的相参特性进行频谱相关消除了相位模糊，并放大了多普勒频率变化率信息。
