目　的本研究旨在探討腕動計與睡眠日誌於心臟衰竭病患所測睡眠參數間之一致性。方　法共計43位心臟衰竭個案參與本研究，年齡範圍為40至92歲。每位個案佩戴腕動計七天並同時填寫睡眠日誌七天，各睡眠參數值由七天平均結果計算。結　果腕動計與睡眠日誌所測得之睡眠中斷醒來時間與總睡眠時數有顯著差異（p < .001），且腕動計所測得之睡眠中斷醒來時間與睡眠潛伏期結果均與睡眠日誌所測結果並不相關。以Bland-Altman分析發現兩種測量方式於睡眠中斷醒來時間之平均誤差達54.1分鐘（SD = 47.5），而總睡眠時數平均誤差達109.3分鐘（SD = 91.68）。83.7%的個案由腕動計偵測出有睡眠障礙，但睡眠日誌結果顯示僅53.5%的個案有睡眠障礙。結　論腕動計與睡眠日誌於心衰竭病患所測得之各睡眠參數值有相當程度之不一致。

Background: Quality of life in patients with heart failure (HF)can be significantly impacted by poor sleep and its daytime consequences. As more attention is being paid to the sleep problems of HF patients, it is important to evaluate the degree of congruence between subjective and objective sleep measurements in this patient group.Purpose: This study was developed to evaluate the congruence between sleep parameters as measured using a wristworn ActiGraph and a daily sleep log in patients with stable HF.Methods: Forty-three HF patients aged 40–92 years served
as subjects. Sleep parameters were derived from actigraphy and a daily sleep log by averaging scores for 7 nights.Results: There were significant differences in wake time after sleep onset (WASO) and total sleep time between the sleep log and the ActiGraph (both ps G .001). Neither WASO nor sleep onset latency, both derived from the sleep log, correlated significantly with actigraphy variables. The mean bias
for WASO and total sleep time between methods was 54.1 min (SD = 47.5 min) and 109.3 min (SD = 91.68 min) as assessed using a Bland–Altman analysis. A majority (83.7%) of participants experienced sleep disturbances as assessed by actigraphy. However, fewer (53.5%) had sleep disturbances as assessed using the sleep log.Conclusion: A considerable degree of incongruence between actigraphy- and sleep log–derived measures of sleep exists in patients with stable HF.
