Abstract:
In foreign country, lots of studies were reported about the relationship between heart rate variability (HRV) and cardiac mortality. Lower HRV has been identified as a independent risk factor for sudden death. By the time, the study of HRV is confined to physically diseased state such as myocardial infarction or diabetic neuropathy. However recently the tendency of HRV has been toward to make clear the relationship of HRV and psychological problem. It is well known that depressed person is affected frequently by cardiovascular disease compared with normal people. However the mechanism that depression increases cardiovascular disease is not definitely found even though the autonomic dysfunction measured in HRV is suggested a factor for this mechanism. Depressed person has decreased HRV, decreased low frequency which reflects sympathetic activity, decreased high frequency which reflects parasympathetic activity. It means they have lower autonomic activity, so they have high cardiac mortality. Few physician knows about the utility of heart rate variability and in my thought, especially short time analysis and frequency domain method is first introduced in Korea. So we introduce this case for as many as physician know the utility of HRV.
