METHODS: In 121 children (40 cases of simple STT changes, 40 of viral myocarditis with STT changes and 40 normal children), 24 h Holter monitoring were conducted and all HRV parameters (including time domain and frequency domain) were analyzed, and the ECG changes during waking and sleeping periods was observed. With ST depression as dependent variables, all HRV parameters as independent variables ,multiple regression analysis was carried out. RESULTS: In the pure STT change group, HRV was increased, HF being 1465±197 vs 497±201 (P<0.017); the alteration between sleeping and waking periods was more obvious as compared with normal group. In STT
