The purpose of this study was to investigate the quality of life (QOL) in patients before and after permanent pace make rimplantation. A follow-up study design was adopted and purposive sampling was applied to recruit subjects from two mcdical centers in Taipci City. Subjects were inter viewed before pace maker implantation. Follow-up inter views were con ducted at second, fourth, and sixth month after pace make rimplantation. There were 42 subjects enrolled in this study. These subjects had moderate QOL (62.4±15.9 on a scale of 97) before pace maker implantation and the QOL improved significantly after pace maker implant tation (p<05). The QOL improvement reached a peak at the end of the fourth month and the scores decreased at the end of the sixth month vs. the fourth month (p<05). They hadsignifi cant improvement in “general well-being”, “sleeping”, “appetite”physical activity”,and“phys icalsymptoms”(p<05), but not in “cognitive function”, “social participation” ,“work capability” and “sexual function” (p<05). Subjects with spouses as their main care givers had significantly better improvement in QOL after pace maker implantation. Subjects’perceptions of distress fom arrhyth miawere the most significant determinant in their QOL pre and postpace maker implartation. The findings suggest that aggressively resolving arrhythmia distress is important for improving QOL.
