摘要：
After analysing the f (a) singularity spectrum of the ST segments of the synchronous 12-lead ECG, it is found that the singularity spectrum is close to monofractality and it's area is only half of the synchronous 12-lead ECG f (a) singularity spectrum. The ST segments of. the synchronous 12-lead ECG signal also has f (a) singularity spectrum distribution which locating under the synchronous 12-lead ECG signal J'(a) singularity spectrum distribution and it also has a reasonable varying scope. It is found the lead number of the ST segment f (a) singularity spectrums for adults having coronary heart disease overstep the reasonable scope tends to increase over that of the ECG f (a) singularity spectrums. It is showed that the use of ST segments f (a) singularity spectrum distribution of the synchronous 12-lead ECG is more effective than that of the synchronous 12-lead ECG in clinical analysis.
