ECG:①Atrial fibrillation (15 cases),Left bundle branch block (LBBB,6 cases),Ventricular presystole 17 cases,nonsustained VP and sustained VP were 9 and 5 cases respectively,and all the latter died.

心电图：①房颤15例，左束支传导阻滞(LBBB，6例)；②室性早搏(VP，17例)；③非持续性室早搏和持续性早搏分别占9例和5例(后5例均已死亡)。

AMs that collected, pured and cultured with contine method were stimulated by LPS of different concentration(0μg/ml,0.01μg/ml,0.1μg/ml,1μg/ml,10μg/ml) for 60min or by 1μg/ml LPS for different time stage (0min,5min,15min,30min,60min,120min) to observe the dynamic change of NF-кB intranuclear level and NO production, from which the best concentration and time point of LPS stimulation were selected. In the study, all AMs were divided into 4 groups: control group, group stimulated with LPS, group interrupted by Cal C and group inhibited by PDTC. The following parameters were measured: NF-кB level in nuclear protein extraction of AMs detected with sandwich ELISA, Inter-nuclear transposition of NF-кB observed with immunocytochemistry staining, NO content in cell culture medium quantitied with nitric acid reductase assay, Morphologic change of AMs in apoptosis observed with acridine orange staining and fragmentation at genome DNA of AMs detected with apoptotic electrophoresis assay.
