有人假设QRS波高频(150—250Hz)成份的振幅(均方根电压)增大,出现于溶栓治疗成功再灌注时,而溶栓治疗失败时则无此现象。溶栓治疗后出现或不出现再灌注的临床标志很不敏感。缺血期间QRS波高频成份的振幅降低;缺血解除后QRS波高频成份的振幅恢复正常,但是迄今尚未见到有关描述急性心梗过程中QRS波高频成份测定的变异及改变类型的工作。在32例健康对照者中
It was hypothesized that the amplitude (root mean square voltage) of the components of high-frequency (150-250 Hz) QRS waves increased after successful thrombolytic therapy, whereas thrombolytic therapy failed. Clinical signs of reperfusion with or without thrombolysis are very insensitive. The amplitude of the high frequency component of QRS wave decreased during ischemia; the amplitude of QRS wave high frequency component returned to normal after ischemia, but so far there are no reports on the variations and types of changes in the determination of high frequency components of QRS wave during acute myocardial infarction jobs.
