Objective To explore the impact of phased rehabilitation training under multidisciplinary collaboration on cardiac function in patients after pacemaker implantation.Methods A prospective study design was used,including 98 pacemaker implantation patients treated at Xianyang Central Hospital from January 2020 to December 2022.The patients were divided into an experimental group(49 cases)and a control group(49 cases)based on the admission order.In the experimental group,there were 25 males and 24 females,aged(60.52±7.21)years,and the type of pacemaker implantation was single-chamber pacemaker in 20 cases and dual-chamber pacemaker in 29 cases.In the control group,there were 26 males and 23 females,aged(60.78±7.09)years,and the type of pacemaker implantation was single-chamber pacemaker in 21 cases and dual-chamber pacemaker in 28 cases.The control group received routine postoperative care,and the experimental group underwent phased rehabilitation training under multidisciplinary collaboration on the basis.The intervention lasted until 3 months after surgery in both groups.The intervention effect was evaluated by exercise endurance(6 min walking distance),cardiac function[N-terminal pro-B-type natriuretic peptide(NT-proBNP)and left ventricular ejection fraction(LVEF)],upper limb mobility,complications(bleeding,infection,shoulder pain,and lead dislodgment),and comfort level[General Comfort Questionnaire(GCQ)score].Independent sample t test and x2 test were used for statistical methods.Results After intervention,the 6-min walking distance of the experimental group was(290.14±34.16)m,which was longer than that of the control group[(138.75±14.34)m],the level of NT-proBNP was(262.11±68.12)ng/L,which was lower than that of the control group[(398.93±76.69)ng/L],and the LVEF level was(69.82±4.73)％,which was higher than that of the control group[(52.53±5.44)％],with statistically significant differences(t=28.604,9.337,and 16.789,all P＜0.05).At 3 months after surgery,the ranges of motion in adduction,abduction,flexion,and extension in the experimental group were(18.27±6.02)°,(52.67±10.33)°,(64.37±7.14)°,and(22.78±3.96)°,which were greater than those in the control group[(12.78±5.39)°,(45.34±9.33)°,(51.36±6.93)°,and(18.61±3.78)°],with statistically significant differences(t=4.756,3.686,9.153,and 5.332,all P＜0.05).The incidence of complications in the experimental group was 4.08％(2/49),which was lower than that in the control group[16.33％(8/49)],with a statistically significant difference(x2=4.009,P=0.045).After intervention,the GCQ scores for environmental,physiological,sociocultural,and psychological dimensions of the experimental group were(3.72±0.67),(3.24±0.53),(3.90±0.42)and(3.68±0.54)points,which were higher than those of the control group[(2.38±0.42),(2.49±0.36),(2.75±0.27),and(3.17±0.35)points],with statistically significant differences(t=11.537,7.951,15.276,and 5.431,all P＜0.05).Conclusion Phased rehabilitation training under multidisciplinary collaboration has a positive impact on postoperative outcomes for patients with pacemakers,improving the exercise endurance,cardiac function,and upper limb mobility,and reducing the complications,thereby enhancing their comfort and daily self-care abilities,with significant clinical value.
