扩张性心肌病频域心电图(FCG)主要表现为传递函数、脉冲响应及相干函数的异常。肥厚性心肌病 FCG 表现为相关函数 R_1过高。脉冲响应正向峰过低,功率谱2峰过高为心肌病共同特点。
Dilated cardiomyopathy frequency-domain electrocardiogram (FCG) mainly for the transfer function, impulse response and coherence function abnormalities. Hypertrophic cardiomyopathy FCG showed a correlation function R_1 is too high. The impulse response positive peak is too low, the power spectrum 2 is too high for common features of cardiomyopathy.
