为探讨激光心肌血运重建术对急性心肌缺血性损伤的作用。应用Nd :YAG激光光纤传输其能量照射犬急性心肌缺血区 ,观测造成微小心肌管道后对胸前多导程心电图及血清磷酸肌酸激酶活性的动态变化的影响。结果发现 ,激光单腔道组心电图ST段偏移总和 (∑ST)为 42 .3± 12 .8mm ,ST段异常抬高点数 (NST)为 6 .5± 1.3,激光多腔道组∑ST为 2 0 .1± 6 .72mm和NST为 5 .3± 0 .6 ;分别低于和明显低于激光照射前的∑ST 80 .4± 2 4.2mm及NST 9.8± 1.1(P

Aim To investigate the effects of transmyocardial laser revascularization (TMLR) on acute myocardial ischemic injuries. Methods Nd: YAG laser with a guartz optical fiber was treated to irradiate the canine acute myocardial ischemic area and the dynamic changes of epicardial ST-segment electrocardiograms serum creatine kinase level were measured following TMLR. Results The deviant summation of ST segment (∑ST) in single channel group was 42.3±12.8 mm, the total numder of extraordinary elevation point in ST segment(NST) was 6.5±1.3 and ∑ST in...
