| Summary: | 碩士 === 臺北醫學大學 === 護理學研究所 === 96 === The purpose of this study was to investigate the relationship between physical activity and heart rate variability in orthoropic heart transplant recipients, the difference of heart rate variability between the the client under orthoropic heart transplant for one year and the healthy matching age, gender and physical activity with orthoropic heart transplant recipients. Seven-day Physical Activity Recall questionnaire was used to collect the subject’s physical activity amount per week. The data were analyzed by percentage, mean, standard deviation, frequency, t-test, Chi-Square, and pearson correlation.
The major findings of this study were the following: heart transplant recipient’s heart rate variability in terms of mean, sdr, TP(ms2), LF(ms2), LF(nu), HF(ms2), and LF/HF were significantly less than the healthy
(p<.05). Heart transplant recipient’s heart rate variability parameters including TP(ms2), LF(ms2), HF(ms2)and LF/HF’s data were only at the healthy’s 17.8%, 2%, 7.3% and 44%; respectively in the case of heart transplantation, relative amount of moderate physical activity was positively related to the sdr (r=.409, p=.015), TP(ms2)(r=.428, p=.01) and HF(ms2) (r=.422, p=.012), but negatively related to the LF(nu) (r=-.337, p =.048). Absolute amount of moderate physical activity was also positively related to the sdr (r=.424, p=.011), TP(ms2)(r=.453, p=.006) and HF(ms2)(r=.466, p=.005). The result confirms the more amount of moderate physical activity, the better heart rate variability is.
The result of this study would be valuable for caring and enhancing the quality of health care of heart transplant recipients.
