Abstract: ObjectiveTo evaluate the quality of life of the patients with different mode of cardiac pacemaker implantation with the SF-36 Chinese version.MethodsOne hundred and twenty-two cases of patients with different mode of permanent pacing were investigated before and after the operation with the SF-36 Chinese version.ResultsSuccessful surgeries on 121 cases were carried out and surgery on one case was unsuccessful.The original cardiac symptoms of 121 patients were improved in different degress after the operation.The scores of SF-36 in 8 aspects of the patients after the operation was higher than that of before the operation(P<0.01 or P<0.05)except for body pain dimension.The preoperative and postoperative scores of the patients with single lumen pacemaker were as following:physical functioning,54.1±20.5 vs 66.8±19.4(P<0.01);role-physical,26.4±11.6 vs68.8±31.6(P<0.01);bodily pain,94.3±17.7 vs 96.8±19.7(P>0.05);general health,26.5±15.4 vs 50.3±23.5(P<0.01);vitality,46.2±10.9 vs 56.7±15.5(P<0.01);social functioning,35.4±11.8 vs 52.9±17.6(P<0.01);role emotional,22.5±14.4 vs 66.1±19.8(P<0.01);mental health,46.3±9.6 vs 58.3±13.8(P<0.01);reported health transition,40.1±12.5 vs 56.7±19.2(P<0.01).The preoperative and postoperative scores of the patients with dual chamber pacemaker were:physical functioning,60.3±14.2 vs 75.4±13.1(P<0.01);role-physical,25.0±11.3 vs 71.9±27.2(P<0.01);bodily pain,95.3±17.7 vs 97.8±19.7(P>0.05);general health,97.8±19.7 vs 58.1±15.9(P<0.01);vitality,48.2±15.7 vs 63.8±13.4(P<0.01);social functioning,38.3±12.7 vs 60.6±15.4(P<0.01);role emotional,17.1±8.3 vs 61.9±30.1(P<0.01);mental health,48.6±8.3 vs 64.5±11.5(P<0.01);reported health transition,42.7±9.1 vs 64.4±16.9(P<0.05),respectively.There were better therapeutic efficacies in patients with dual chamber pacemaker than those with single lumen pacemaker.ConclusionThe quality of life of patients with permanent pacemaker is improved in physiologic and psychosocial function after the operation.It is important to select physiological pacing mode according to patient's condition to enhance the quality of life of the patients after the operation.
