RESUMO
Objective:To explore clinical significance of sinus heart rate turbulence (HRT) phenomenon in aged pa‐tients with stable angina pectoris (SAP) .Methods :A total of 120 aged SAP patients ,who received 24h DCG in our hospital from Jan 2013 to Oct 2015 ,were selected as SAP group .Meanwhile ,another 144 aged patients ,who re‐ceived 24h DCG examination simultaneously and coronary angiography results were normal ,were regarded as nor‐mal control group .According to coronary lesion severity ,SAP group was further divided into single vessel coronary disease group (single vessel group ,n=35) ,double‐vessel coronary disease group (double‐vessel group ,n=48) and multi‐vessel coronary disease group (multi‐vessel group ,n=37) .The 24h DCG ,HRT indexes ,including turbulence onset (TO) and turbulence slope (TS) ,were measured and compared among all groups .Results:Compared with normal control group ,there was significant rise in TO [(0.77 ± 0.37)% vs .(1.26 ± 0.92)% ] and significant reduc‐tion in TS [(5.45 ± 4.02) ms/RR interval vs .(1.53 ± 0.70) ms/RR interval] ,P<0.01 both ;significant rise in ab‐normal rates of TO (19.44% vs .42.50% ) ,TS (15.97% vs .31.67% ) and TO + TS (11.11% vs .30.83% ) in SAP group ,P<0.01 all .Compared with single vessel group ,there was significant rise in TO [(0.66 ± 0.22)% vs .(1.28 ± 1.11)% vs .(1.46 ± 1.20)% ] and significant reduction in TS [ (2.04 ± 0.82) ms/RR interval vs .(1.66 ± 0.38) ms/RR interval vs .(1.29 ± 0.58) ms/RR interval] in double‐vessel group and multi‐vessel group ,and TO of multi‐vessel group was significantly higher than that of double‐vessel group ,TS of multi‐vessel group was significantly low‐er than that of double‐vessel group , P<0.01 all .Conclusion:Sinus heart rate turbulence can be used as risk predic‐tor for aged patients with stable angina pectoris ,which can provide basis for clinical effective treatment and progno‐sis assessment .
RESUMO
Objective To study the application effects of from-bottom-to-up objective management model in nursing quality control.Methods Eight surgical departments in our hospitals were selected as research objects.Traditional objective management model was applied in the control group (8 004 cases,9 453 visiting times) from June 2012 to June 2013.From-bottom-to-up objective management model was applied in the experimental group (8169 cases,9 603 visiting times) from July 2013 to July 2014.Nursing work quality and continuous improvement projects were compared between two groups by questionnaire survey,a return visit by telephone and statistical evaluation.Results The satisfaction of patients with nurses' service attitudes and professional technology level and the awareness of patients about major nurses in the experimental group were significantly higher than those in the control group [95.56％ (7 806/8 169),95.19％ (7 776/8 169),97.17％ (7 938/8 169) vs.93.22％ (7 461/8 004),92.62％ (7 413/8 004),84.60％ (6 771/8 004),allP＜0.01].Patient complaints and the incidence of nursing adverse events in the experimental group were significantly lower than those in the control group (46,16 cases vs.85,39 cases,x2=9.783,P＜0.01).Conclusions Applying from-bottom-to-up objective management model could cultivate self-control abilities and innovation awareness of nurses,which can improve nursing work quality.
