@entity1165 ( @entity1165 ) and @entity2224 ( @entity2224 ) leading to @entity1164 remains responsible for significant mortality in @entity1 with prior @entity583 ( @entity583 ). The study population consisted of 50 normal controls and 50 @entity1 with prior @entity583 . The @entity583 subjects were divided into 3 groups: @entity1165 / @entity2224 (-) group; 25 @entity1 without @entity1165 , @entity1165 group; 13 @entity1 with sustained @entity1165 , and @entity2224 group; 12 @entity1 with resuscitated @entity2224 . The parameters on the signal-averaged ECG and the frequency components recorded from the wavelet-transformed ECG were compared. The high-frequency components (HFC; 80-150 Hz) were developed in the @entity583 group to a greater extent than those in the control group. Among the @entity583 @entity1 , the HFC were more developed in the @entity1165 and @entity2224 groups than in the @entity1165 / @entity2224 (-) group. In the @entity2224 group, the positive rate of LP was 50%. Meanwhile, when the peak power value at 150 Hz > 300 was defined as abnormal, the @entity3708 was detected in 13 (100%) @entity1 in the @entity1165 group and 12 (91.7%) in the @entity2224 group. The sensitivity of the abnormal HFC in identifying @entity1 with @entity1165 / @entity2224 was higher than that of SAECG (96% versus 72%), although the specificity remained similar (68.5% versus 64.3%). Abnormal HFC recorded from the wavelet-transformed ECG may be a novel factor in detecting @entity1 who are prone to @entity1165 / @entity2224 .
